The ''Prism Pentad'' is a series of five books written by Troy Denning and set in the world of [[DarkSun Athas]].

The desertic wastelands of Athas are ruled by the despotic Sorcerer Kings, and Borys, the legendary Dragon, roams in the desert and force the Sorcerer Kings to pay him a tribute of a thousand slaves each year. In this [[CrapsackWorld grim land]], a small and improbable band of heroes ([[CulturedBadass Agis of Asticles]], [[BaldOfAwesome Rikus the half-dwarf]], [[ActionGirl Neeva the gladiator]], [[TheSmartGuy Sadira the half-elf]] and [[TokenEvilTeammate Tithian of Mericles]]) fights for the freedom of their home town, Tyr. Eventually, their path will lead them to a great battle with the fate of Athas itself at stake.

The books are:
* ''The Verdant Passage'': Where our heroes gathers and start a quest in order to defeat the dispotical Sorcerer King Kalak of Tyr.
* ''The Crinsom Legion'': Narrates Rikus' battle against the invading armies of King Hamanu. However, he'll have to endure many trials in order to succeed.
* ''The Amber Enchantress'': Sadira starts a dangerous journey in order to reach the legendary Tower of Primords, in order to find a power strong enough to stop Borys.
* ''The Obsidian Oracle'': Where Agis chase after Tithian in order to arrest him and recover the Obsidian Lens, the artifat required for slaying the Dragon. [[spoiler: Sadly things [[DownerEnding ends badly.]]]]
* ''The Cerulean Storm'': Where the final battle against our heroes and the Dragon Borys takes place.

* FantasyCounterpartCulture: Tyr is based on Tyre, Urik on Babylon/Uruk, Nibenay on Ancient China/Angkor, Balic on Greece, Draj on the Aztec empire, Raam on India mixed with a bit of Egypt, Gulg on Africa. Elves here may be seen as Gypsy/Beduin analogues.
* FantasticRacism: The main reason why Rajaat started the great Epuration in the past. Fallen races include Ogres, Orcs, Goblins, Gnomes, Kobolds, Pixies and Trolls.
* FemmeFatalons: Abalach-Re, Sorceress Queen of Raam. Also Lady Joy of the Spirit Lords.

** TheLancer: Rikus/Neeva
** TheBigGuy: Caelum/Neeva
** TheSmartGuy: Sadira

* ForTheEvulz: The Sorcerer Kings. A glaring example is Hamanu, who orders to one of his subordinates to fight a sword-wielding Rikus.... unarmed.

* GeniusBruiser: Sadira post Sun Powers.
* GentleGiant: Fylo, who's one despite being quite gullible.
* GiantFootOfStomping: The giants' main form of attack against other people.
* GiantMook: Half Giants serving the Sorcerer Lords.
* GiantSpider: A friendly aversion inhabiting the jungles of the Ringing Mountains. They're even UglyCute and have a cat-like behaviour. Neeva also mentions that she and Rikus fought several giant spiders during their gladiatorial days.
* AGodAmI: All the Sorcerer Kings. Actually justified, as they're so powerful that they can allow templars to cast spells. This applies especially to Tectucticklay (who claims to be a moon god) and Lalali-Puy (the forest goddess).

* HeroicBlueScreenOfDeath: Happens to several people. The hardest one is [[spoiler:Sadira, after seeing Agis amongst the dead]].
* HeroicSacrifice: [[spoiler:Fylo does a tear-jerking one against a giant attack in order to buy Agis some times. Made even more Tear inducing by the fact that Agis, the only witness, is killed shortly after, making it a senseless sacrifice.]]
* HalfHumanHybrid: Many. In the main circle, Rikus and Rkard (Mul or Half Dwarves) and Sadira (half elf).
* HyperspaceIsAScaryPlace: The Black and The Grey.
* ImplacableMan: Prince Dhojakt in book three. A smell-confusing gas to cover your escape? Worthless. An acid cloud [[PersonOfMassDestruction capable of vaporizing a small army]] [[ThereIsNoKillLikeOverkill right in the nostril?]] He got better. Whole upper body trapped in a giant pearl and the toss in a seemingly-bottomless pit? [[MadeOfIron ''NOT ENOUGH'']].

* LudicrousGibs: What happens to [[spoiler: Caelum when Borys unleashes a full powered [[CurbStompBattle psionic attack on him.]]]]
* MacGuffin: The Heartwood Spear in the first book. The Chronicles of Kemalok in the second. The Power of the Tower of Primords in the third and the Dark Lens in the fourth. The last two are needed along with the Scourge of Rkard to kill Borys.

* PetTheDog: Despite being a slave owner in the first book, Agis was extremely kind with all of his slaves.
* ThePowerOfTheSun: What Caelum and Rkard use. After book 3 Sadira's magic takes its energy from the Sun.
