The Prism Pentad

The Prism Pentad is a series of five books written by Troy Denning and set in the world of 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 grim land, a small and improbable band of heroes (Agis of Asticles, Rikus the half-dwarf, Neeva the gladiator, Sadira the half-elf and 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 succed.
 * 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.
 * The Cerulean Storm: Where the final battle against our heroes and the Dragon Boys takes place.
