The temple archon in the city of Deepgate, Dill is descended from a long line of warriors, included his famous father Gaine, and ultimate ancestor Callis. A sixteen year old boy at the start of the story, Dill is an untrained, naive boy terrified of breaking the rules, yet eager to live up to his ancestors' greatness.
One-Man Army: At the end of Iron Angel, Dill is placed inside of an arconite, a five hundred foot tall mechanical angel in the service of Menoa. He goes rogue and proceeds to slaughter an entire army of Mesmerists, before taking on twelve other arconites.
The daughter of General Edward Hael and sister to Commander Mark Hael, Rachel is the only untempered (read as: possesses emotions) Spine Adept. She is assigned by Presbyter Sypes to train Dill in diplomacy and combat, despite being totally unqualified for the position.
Rape Is a Special Kind of Evil: Expresses this attitude. She once beat up a bunch of soldiers who were raping Heshette women (despite Rachel having killed most of their men herself), and is absolutely disgusted when Ulcis threatens his daughter with it.
A psychotic, badly scarred angel who haunts Deepgate's rooftops, Carnival is a serial murderer and stealer of souls. Once a month, during the new moon, she descends into the city, murders someone, and devours their soul, then cuts herself in order to commemorate the event, causing these evenings to be known as "Scar Night."
The head of Deepgate's church, Sypes is an old, sick man who has devoted his life to Deepgate and the Church of Ulcis. Frequently playing the role of the senile fool, Sypes is far more coherent than he appears.
Arch-chemist and Master Poisoner of Deepgate, Devon's chemical weapons are one of the Church's principle weapons against the outside world. Left sick, dying, and bereft of his beloved wife, Elizabeth, after prolonged exposure to his poisons, Devon is determined to obtain more life and revenge on Deepgate for himself.
Nietzsche Wannabe: Devon believes that everyone in Deepgate is waiting to die and therefore, undeserving of life. The bad thing is that he's not wrong; Deepgate's entire culture is based around waiting to die.
Omnicidal Maniac: About as close as he can get, given the setting. He intends to use the Tooth of God to cut Deepgate's chains and send the entire city plummeting into the abyss.
Woobie, Destroyer of Worlds: Devon is living with constant pain, dying by inches, and alone. Worse yet, he's done it all for a city that despises and fears him. It isn't surprising, honestly, that he cracks.
A scrounger whose daughter's soul was stolen by Devon, Mr. Nettle spends the entire novel on a Roaring Rampage of Revenge, first against Carnival (whom he belives to be the thief), and then Devon. Huge, single-minded, and thuggish, Mr. Nettle refuses to give up, no matter what happens to him.
The god of chains and eldest son of Ayen, goddess of light and life, Ulcis lead the rebellion against her and was cast out of Heaven for it. Residing in the vast abyss Deepgate is built atop of, Ulcis offers humanity an alternative to eternal damnation, and is slowly but surely building an army with which to reclaim Heaven. Except not. He's actually far more interested in conquering the mortal realm and feeding on souls for all eternity than he is in actually going to war with his mother. He's also Carnival's father.
Archnemesis Dad: To Carnival, whom he tried to murder and then had gangraped shortly after her birth.
The Big Bad: Competes with Devon for the title of Big Bad of Scar Night.
Evil Cripple: In a totally self-inflicted way. Ulcis is so fat that he can't fly anymore and can barely walk. He just sort of oozes.
Fat Bastard: So fat, in fact, that his gender is concealed, despite his nudity.
A huge, dark-skinned man from the Riot Coast, Anchor serves as The Dragon to Cospinol, god of brine and fog. Simple-minded and cheerful, Anchor has a live-and-let-live attitude, but is a terrifying fighter when roused, capable of holding his own against the likes of Carnival using only his fists and armour made of living crabs. His name is taken from his primary task: tethered to the end of a massive rope, Anchor walks the earth, dragging Cospinol's flying ship, the Rotsward after him.
Armour Is Useless: Averted. Anchor's armour—made up of thousands of living crabs—keeps him safe from anything the world can throw at him.
Your Soul Is Mine: Indirectly. Anchor doesn't steal souls, but those he slays become a part of Cospinol's ship, where they are turned into soul pearls, and given to Anchor to eat, making him even stronger.
A dead woman in service to the Mesmerist cause, Alice Harper served as one of King Menoa's engineers in life, and now continues to serve him in death. Despite her many successes on his behalf, she is constantly tortured and forced to assume new forms by Menoa, who values her services, but values his sadism more. She eventually betrays him and sides with Rys' forces.
Body Horror: Forced to undergo it repeatedly at Menoa's hands.
The leader of the Mesmerists, King Menoa is ruler of Iril, the Maze of Hell, and the chief opponent of Rys, Sabor, and the other children of Ayen. Seeking to reduce the world to a state of constant change and flux, Menoa sends his servants into the world through portals caused by bloodshed, raising hordes of demons, building infernal machines, and attempting to tamper with the time stream itself in the hopes of gaining dominion over all creation. He is Ayen's bastard (and favourite son) by a mortal lover, who killed himself in order to save her life during the War in Heaven, and was damned to Hell. He then overthrew Iril, Ayen's husband, and sought to avenge himself on his brother's.
Bad Boss: Tortures his followers or forces them to assume new shapes as it pleases him.
Omnicidal Maniac: Seeks the destruction of this universe and ultimately the erasure of the entire time stream.
Out-Gambitted: Does it to Rys at the end of Iron Angel, using the blood of his own army to raise twelve new arconites. Has it done to him by Sabor at the end of God of Clocks, despite managing to ensure the latter's death at Hasp's hands.
Parental Favouritism: Is Ayen's favourite son, and remains so even after she discovers what he's done.
The Reveal: Comes in God of Clocks courtesy of Sabor.
You Have Failed Me: More like "you have served me well. Here, I'm going to warp your body so that you can serve me even better. Ha ha."
The god of flowers and knives, and leader of Ayen's remaining sons, Rys is worshipped throughout the North, where his people cut knives into their own flesh in worship of him. Arrogant, self-centred, and charismatic, Rys fights an unending war against Menoa and his Mesmerists for dominion over mankind.
Take Over the World: Wants the entire world to worship him, and hopes to reduce humanity to nothing more than slaves. Still a better option than Menoa though.
Tykebomb: Rys' soldiers are selected from birth, and forced to wear armour that contains blades on the inside. As they grow older their bodies grow around the knives, either killing them, or making them the toughest soldiers in the world.
The god of brine and fog, Cospinol is the only one of his brothers, save for Ulcis, who has failed to escape from his prison. Kept aboard his slowly rotting ship by Ayen's curse, Cospinol is dependent upon John Anchor to keep his ship moving and be his voice in the outside world. He is roped into helping Rys' plans during the beginning of the novel, and sets out with Anchor to capture Carnival.
Antivillain: Cospinol is an antagonist to Rachel, Carnival, and the rest of the cast, but he's only a villain in the same sense that Rys is a hero.
Cruel and Unusual Death: Torn apart and devoured by Carnival in God of Clocks, a fate that he definitely did not deserve given his generally sympathetic nature, and the fact that he was aiding the heroes by the end.
Stronger Sibling: He and Rys are both this to Ulcis, moving on Deepgate the moment that their older brother falls. While Cospinol isn't much of a fighter, he's certainly tougher than Ulcis was, and John Anchor's presence makes him truly dangerous.
The youngest of Ayen and Iril's sons, Hasp is Master of the First Cathedal and leads the battle against King Menoa from within Hell. He takes a shine to Dill, and does his best to instruct the young angel in swordsmanship and the art of war, before Menoa comes for them both. Contaminated by a Mesmerist parasite, Hasp is forever after forced to do the bidding of any of Menoa's followers.
The Alcoholic: Spends most of God of Clocks at the bottom of a bottle.
The god of clocks, Sabor is introduced in Iron Angel but does not really come into his own until the novel that bears his title. Sombre, colourless, and unemotional, Sabor spends most of his time operating behind the scenes, battling King Menoa for control of the time stream, creating a myriad of alternate universes in the process.
The Chessmaster: The only who can rival Menoa. Sabor is engaged in a massive plot that spans entire time streams and universes, yet somehow manages to keep all the strings firmly in place.
Expendable Alternate Universe: Escapes the fate of his brothers by leaving a "temporal copy" to die in his place. It is worth noting that the copy agreed with this plan.
Only Sane Man: Ulcis is a monster, Rys is narcissistic prick, Hafe is a fat slob more concerned with eating than anything else, Merith is mad, Cospinol is a sad old man waiting for the end, and Hasp has Menoa's parasite screwing with his brain. Sabor is the only one of the gods to have his head in a place remotely resembling reality.
Out-Gambitted: Which results in his death at Hasp's hands. He gets the last laugh though, as the plan he sets in motion ultimately still succeeds in derailing Menoa's own plans.
Well-Intentioned Extremist: Sabor is a ruthless guy who's willing to go to almost any lengths if it means making his plans work. Since his plan roughly boils down to "stop satan from ending the multiverse" this is understandable.
Goddess of light and life and mother of the other gods, Ayen closed heaven following her husband's murder of a mortal she was having an affair with, prompting her sons to revolt against her. She takes the appearance of an old woman, and has little idea of what is actually going on in the world.
