Heralds are divine servants of the gods, each a unique being that functions as messenger of their master and a fragment of divine power followers can summon to aid them.
All heralds except the Spawn of Rovagug have a Challenge Rating of 15.
Core God Heralds
The herald of Nethys, created out of raw magic to serve him.
- Barrier Change Boss: When subject to any effect, the Arcanotheign is always treated as the most favorable alignment subtype pertaining to that effect.
- Intangibility: She's incorporeal by default, although she can take a corporeal form in case she needs some muscle.
- Made of Magic: Appropriately enough for the chief servant of the god of magic. The best way to describe her is a sort of magic elemental.
- Nature Lover: She is interested in animals, and her habit of animating animals out of earth, stone or wood represents her respect for animals she has known in the past ages.
- Sense Freak: The Arcanotheign understands she is foreign to mortal life and needs. She enjoys experiencing new aromas and tastes; someone wishing to get on her good side should bring her strongly scented flowers, a tasty meal, or some other physical object that may be new to her experience, even if normal people would find it gross.
- Shock and Awe: She resembles a vaguely feminine cloud of lightning and ionized gas, and it has cloudkill and lightning bolt in her arsenal of spell-like abilities.
- Statuesque Stunner: She stands just over 7 feet tall.
- You Don't Look Like You: For some reason the picture of her in Inner Sea Gods looks completely different than the orginal (which was a lot more feminine, whereas this one just looks like a vaguely woman-shaped Energy Being).
The herald of Asmodeus.
- Artificial Human: Asmodeus personally created Basileus because all the other archdevils he previously promoted to herald tried to unseat him.
- The Dreaded: Basileus rarely appears on the mortal planes, but when he does, he's "the greatest terror of the age", even to Asmodeus' own followers.
- Hot as Hell: He looks like a Fallen Angel wearing nothing but a black strip of cloth spiraling around his body. Aside from the Slasher Smile, he's pretty damned handsome if you're into that sort of thing.
The herald of Gorum, forged from a fragment of his sword.
- Animated Armor: In its normal form, it's a 15-foot tall, 5-ton Golem shaped like whatever style of armor is most intimidating to its beholders.
- Extra-ore-dinary: Many of its spell-like abilities involve manipulating metal. It can even transform into a cloud of shrapnel.
- Person of Mass Destruction: Calling the First Blade a "person" is a stretch, but it's sapient. It's also capable of single-handedly reducing an entire battlefield to craters and corpses, and its rage aura allows others to join in the carnage.
The herald of Torag.
The herald of Erastil.
- Badass in Distress: In Wrath Of The Righteous, he's kidnapped by the demon lord Baphomet and needs to be rescued from the Ineluctable Prison.
The herald of Abadar.
The herald of Urgathoa.
The herald of Irori.
The herald of Gozreh.
The herald of Zon-Kuthon. Once a noble spirit and the father of Zon-Kuthon, the Midnight Prince twisted and warped his own father into the abomination he is today.
The herald of Shelyn.
- Winged Humanoid: It typically takes the form of a winged human or elf.
The herald of Norgorber.
The herald of Pharasma.
The herald of Sarenrae.
The herald of Cayden Cailean. Thais was a prostitute and close friend of Cayden in his Adventurer days. Cayden repaid her friendship by promoting her to the position after her death.
- Adaptational Nice Guy: She's based on one of Alexander the Great's consorts, but is presumably a lot nicer than the real Thais was — she never helped burn down a city, for one.
- Hard-Drinking Party Girl: As the herald of the god of alcohol this is pretty much a given.
- Historical Domain Character: She's loosely based Thaïs, a prostitute who accompanied Alexander the Great.
- Hooker with a Heart of Gold: In her mortal life, she was a sex worker and a very close and genuine friend of the then-nobody Cayden.
- Stripperiffic: Thais dresses in scandalous ribbons that offer little in terms of modesty.
The herald of Lamashtu.
- Mix-and-Match Critters: A gigantic, monstrous jackal with batlike wings and a viper for a tail.
The Spawn of Rovagug
All Spawn of Rovagug are Chaotic Evil Colossal-sized magical beasts.
- Healing Factor: All of them can heal rapidly.
- Immortality: They flat-out will not die. Even disintegrating their remains isn't enough to keep them dead forever.
- Kaiju: They're all Colossal, the largest size category in the game, and they wreak destruction across Golarion. Design-wise, they occupy a kaiju-lite role, being smaller (except for Ulunat, none has the Massive rule, which is used for the biggest creatures in the game) and weaker (CR 20 to 25) compared to real kaiju (CR 25 to 30). Spawn of Rovagug are designed to occupy the role of Final Boss against a 20th level party, while kaiju are designed for a higher gameplay role, including a game where fighting the monster isn't so much the goal of a campaign as it would be preventing the fight from having to happen.
- No-Sell: All the Spawn are outright immune to ability damage, bleed, disease, energy drain, mind-affecting effects, paralysis, permanent wounds, petrification, poison, and polymorph effects. Each is also immune to two energy types, which just seems excessive, and all have damage resistance that negates any attacks that don't deal more than a certain amount of damage.
- Rip Van Winkle: They can hibernate for centuries at a time, gaining massive damage resistance in the process, as well as immunity to divination effects, any magic that allows for magic resistance, and the need to breathe.
- Single Specimen Species: They're magically created by Rovagug, so thankfully only one of each exists.
- Super Empowering: Cultists of Rovagug used a ritual to open a direct link between Rovagug and Ulunat when it first emerged, teaching the god how to mark its creations as heralds rather than mere beasts. Granted, there wasn't any change in behavior and they were already strong enough that it didn't do a lot, but it's the thought that counts. Though technically it does provide a substantial power boost, but it takes time for that to set in and the Spawns' rampages means they're often imprisoned or slain before they can make the most of it.
- There Is Another: There are at least a dozen Spawn, but only six are known to have been heralds.
Tarrasque, the Armageddon Engine
The most recent and strongest yet of Rovagug's spawn. It was defeated by a massive effort of combined forces, sealing it in a cavern and driving it into hibernation.
- Adaptational Villainy: In Dungeons & Dragons (and in the original Pathfinder Bestiary), the Tarrasque was a Non-Malicious Monster that was only barely sentient and only rampaged out of instinct. On Golarion, it is Chaotic Evil rather than True Neutral and is the favored child of an Omnicidal Maniac Eldritch Abomination.
- Big Eater: It eats kingdoms.
- Establishing Character Moment: To paraphrase the first line of its history, "Tarrasque emerged from the Pit of Gormuz and destroyed the nearby nation of Ninshabur." Yes, its establishing moment was to annihilate an entire nation.
- Extreme Omnivore: As in Big Eater, it eats kingdoms.
- From a Single Cell: Its regeneration cannot be suppressed, not even by Wish, Miracle, or Mythic abilities to suppress regeneration.
- Healing Factor: Has the largest regeneration in the game, at 40 per turn.
- Hero Killer: Tarrasque is one of the Spawn of Rovagug, god of destruction. It is the biggest, baddest monster in the entire world. It has utterly destroyed multiple empires.
- The Juggernaut: There is a reason this is called the Armageddon Engine. On the defense, it has regeneration, damage reduction, spell resistance, and high hit points. It has mobility from a Rush ability and from Powerful Jumper. It has six powerful attacks per turn, with exceptional reach on each. In short, it it absurdly hard for most people to knock it out, nothing that exists can make it stay down, and it will just keep coming even after the kingdom has fallen.
- Just Eat Him: Has the Swallow Whole ability, for a large amount of damage.
- Kaiju: Has the appearance of one, complete with spiked shell and tremendous power.
- Nigh-Invulnerability: It possesses the trifecta of obscenely high hit points, damage reduction, and regeneration.
- Public Domain Character: The creature derives from a medieval French legend. It was adapted into Dungeons & Dragons early on and gained a reputation as the game's most deadly (non-epic) monster.
- Spell My Name with a "The": It was originally "The Tarrasque," but it was later clarified as a proper noun with the rest of its siblings.
Ulunat, the Unholy First
The first of Rovagug's spawn to crawl forth from the Pit of Gormuz. It rampaged for 473 years before being brought down. In modern times its carapace sits at the center of the Osirian capital of Sothis.
- Antimagic: Of a sort. It has hefty magic resistance, though that can be overcome, but the main danger is its ability to twist magic back on the caster. Target it with a spell? It gets sent back at you as a phantasmal killer. Catch it in the area of a spell? Now you're targeted by insanity.
- Kaiju: It's the largest of the Spawn, towering over entire cities, and is the only one to have the Massive rule, which represents the largest creatures in the game (namely the kaiju, Oaur-Ooung, the Oliphaunt of Jandelay and Leviathan).
- Not Quite Dead: It's been dormant long enough for a city to form around its motionless carapace, but make no mistake, it's not dead.
- Stronger with Age: See that CR 25 rating up there? That's its stats when it first crawled out of the pit. By the time it was brought down it was much, much more dangerous.
Xotani the Firebleeder
Xotani is a burrowing creature, preferring to stay within its tunnels during the day and ravage the land by night. It was defeated by a cabal of mages atop the Pale Mountain, its bones and still-beating heart sealed in a cavern below the peak.
- Bizarre Alien Senses: Xotani uses high-pitched frequencies to sense its surroundings. The spell silence can negate this, but its other senses stops this from crippling it.
- Breath Weapon: It can breath fire every few rounds for quite a it of damage.
- Just Eat Him: It can swallow creatures whole, a process that deals more damage that the identical ability of Tarrasque on account of Xotani's stomach being filled with molten lave.
- My Blood Runs Hot: It's called the Firebleeder, which is very much not an exaggeration. Its blood is essentially lava and damaging it triggers a spray equivalent to a flamethrower.
- Nigh-Invulnerability: It survived magical freezing, submersion in the ocean, and being dropped from really high up.
- Not Quite Dead: It's little more than a heart and skeleton, yet it lives.
- Self-Harm: According to legend, Xotani gouged its own eyes out when it first saw the sun. The fact that it still has eyes doesn't disprove this, given its regenerative capabilities, so it's entirely possible it's true.
- Tunnel King: The heat of its body lets it melt tunnels. It used this ability to cross oceans and attack other continents, but mostly to stay away from the sun.
- Walking Wasteland: Xotani is burning hot, enough that it blighted lands just by being beneath them and letting its heat radiate through the ground. In game, this manifests as bonus fire damage on melee attacks as well as taking damage from hitting it with unarmed or natural attacks rather than a massive death radius.
- Worm Sign: A variant. The land above its passage would be scorched with heat, melting sand into glass and igniting forests.
Chemnosit the Monarch Worm
Chemnosit lurks below the crust of the world, preying on the Darklands rather than the nations of the surface. As a result it's nearly impossible to track down and has yet to be defeated.
- Combat Tentacles: It has six of them, each covered in teeth.
- Evil Is Not a Toy: Chemnosit is the easiest of the Spawn to summon. The key word there is summon, not control.
- Eyes Do Not Belong There: It has one giant eye located in its mouth.
- Horror Hunger: If you fall under its sway, you feel hunger build and build until it surpasses your desire to survive, hunger for the flesh of your own kind. You'll attack your allies, snatch children from the cradle, sink your teeth into your own limbs, doing anything to sate that hunger, eating until your stomach bursts. And then you'll eat more, eat until your body gives out and you die trying to take just one more bite, all under Chemnosit's silent unblinking gaze.
- Hypnotic Eyes: You really don't want to look into its eye. What's that, you already did? Well you must have passed your save, all you feel is tired. And hungry. So hungry. And what's this? Everyone around you, your friends, your family, your allies, they're all delicious meat! I'm sure they wouldn't mind if you sampled the menu.
- Pragmatic Villainy: Most Spawn fight armies directly. Chemnosit just turns its gaze on them and watches, silent and still, as those who fall under its sway go into a cannibalistic frenzy, attacking their own allies and forcing those who resisted to fight their comrades until nothing is left but a few wounded stragglers it can easily devour.
- Silent Antagonist: Chemnosit doesn't usually make noise, which just adds to the horror as it watches in utter silence as armies and cities devour themselves.
- Tunnel King: It rarely ever surfaces, preferring to remain deep below the surface.
Volnagur the Endsinger
A flying beast, Volnagur performed attacks on cities continents apart rather than a concentrated campaign in a specific area. It has supposedly been defeated at least three times, but has returned after each defeat and currently remains at large.
- Brown Note: According to lore Volnagur constantly emits a keening sound that drives those who hear it to madness, violence, and suicide. In game terms, it can cast ''song of discord'' at will, compelling all affected to attack their allies to the best of their ability.
- Eye Beams: It has sonic eye beams that leave victims vomiting blood.
- Giant Flyer: It constantly grows new wings as the old ones atrophy, keeping it aloft on a menagerie of appendages.
- Invisibility: It can turn invisible at will and the effect isn't broken by attacking or casting spells.
- Not Quite Dead: Either it's never been wounded to the point of incapacitation or it has the fastest recovery time of all the Spawn.
- Weather Manipulation: It can control the weather once a day.
Kothogaz, the Dance of Disharmony
Kothogaz spread chaos not only through its own efforts but those of spawned minions and corrupted pawns. It was defeated in a battle said to cost a million lives, after which its heart was extracted and cut into 101 pieces.
- The Corruptor: Its bite causes mutation and madness in those who survive, leaving them dangerously unstable and possessing new and frightening powers.
- Heart Trauma: Its heart was torn out and cut apart to stop it from rising again.
- Mook Maker: Polyp-covered monsters crawl out of the paths it leaves.
- Necromancer: The corpses of those it eats are animated as undead, falling from wounds in its side or vomited from its mouth.
- Not Quite Dead: The fragments of its heart still pulse with life. It's said that if they're ever reunited a new body will grow from them and Kothogaz will be reborn.
- Walking Wasteland: It leaves a trail of fungal slime wherever it goes.
The herald of Milani.
- Angelic Transformation: Courage Heart was originally a Galtan ranger executed by the Red Revolution whose soul was rescued from a final blade by Milani and made into her herald. She still remembers her mortal life and has relatives still living in Galt.
The herald of Ydersius.
The herald of Groteus.
The herald of Zyphus.
The herald of Minderhal.
The herald of Besmara.
- Living Ship: The Kelpie's Wrath is a haunted, sentient ship.
The herald of Lissala.
The herald of Brigh.
