- Friend's Contemplation: Hamanu, replaced 4th Champion of Rajaat, kills Windreaver-the last troll of Athas and king of his people.
- Desert Vengeance: Rkard, the last dwarven king of Kemalok, is slain by Borys of Ebe in mortal combat-though Borys himself is gravely injured. The Champion's attendants spirit him from the battlefield leaving his sword, the Scourge, still buried in the dwarf's chest. Before he can retrieve the sword, Hamanu tells Borys of Rajaat's true plans for Athas. Becoming aware that Rajaat intends to wipe out all races except the halflings, Borys leads the Champions in a rebellion against their master-from which they emerged victorious. Rajaat's halfling servants are banished to the Black as punishment for siding with the War-Bringer. Despite their power, the children of Rajaat cannot destroy his mortal remains. Instead, Gallard separates the First Sorcerer's essence from his physical form, placing each in a separate location. Aided by the power of the Dark Lens, Gallard creates the Hollow, where he placed Rajaat's essence. Gallard then creates a cyst of enchanted stone called the Black Sphere in which he places Rajaat's substance. He then hides the Black Sphere in a location known only to him and Borys of Ebe. Sacha and Wyan, who remained loyal to their master, attempted to breach the cyst before it is hidden away. Their plan is discovered and they are beheaded by Borys. Through the use of the Dark Lens, Borys rewards the remaining Champions by beginning their transformations into sorcerer-kings. This process links each of them to living vortices, which allows them to grant their followers clerical spells. The Champions realize that Rajaat's prison will not hold. Even segmented, Rajaat's power is supreme and he would one day be free. Hence, the Champions once again used the Dark Lens to transform Borys into the Dragon, whose power would keep Rajaat imprisoned for all time. Borys's transformation causes him to become temporarily insane, beginning a century of rampages across the land. In the confusion, two dwarven knights named Jor'orsh and Sa'ram steal the Dark Lens. The remaining sorcerer-kings each claim a city of Athas and barricade it from the rampaging Dragon.
- Friend's Fury: Lead by Abalach-Re of Raam, the sorcerer-kings storm Guistenal and kill Dregoth, Ravager of Giants just before he is to become a 30th-level Dragon. The battle destroys the city, the land, and most of its population. Afterwards, Hamanu throws the Scorcher into the Silt Sea. With the aid of his high templar Mon Adderath, Dregoth is returned to life as an undead dragon king. The surviving populace is gathered soon after, and construction of New Guistenal begins.
165th King's Age (-1,925)
- Wind's Defiance: Borys emerges from his insanity and learns Rajaat's prison is on the verge of collapse. Soon after he collects a levy of 1,000 slaves from each sorcerer-king, using their lifeforce to reseal the First Sorcerer's prison on a yearly basis.

- Ral's Agitation: In an attempt to increase her power, Sielba, Queen of Yaramuke attacks Urik. Hamanu easily defeats her army and personally slays the sorcerer-queen. On the heels of victory, Urik's army sacks Yaramuke and burns the city to the ground. To appease the Dragon's wrath for killing a sorcerer-queen, Hamanu presents Borys with a levy of Yaramuke's riches-which pleases the beast and spares Urik.
- Silt's Defiance: Borys uses the booty gained from Yaramuke to build Ur Draxa, which becomes the greatest city on all of Athas. At the center of the city Borys places the Black Sphere for him and his city to protect.

- Silt's Reverence: Daskinor Goblin Death slips into insanity following this year's levy, and builds an army to slay the Dragon upon his return the following year. Borys learns of his plot, and not needing the levy to maintain Rajaat's prison never returns. Keltis, Lizard Man Executioner, has an attack of conscience and denounces being a sorcerer-king. Over the next centuries he strives to become something more noble. Because of the actions of nearby Daskinor, Borys never returns to Kurn and both cities become isolated from the rest of Athas.

- King's Contemplation: In an effort to increase his power, Kalid-Ma attempts to further his dragon metamorphosis to a power near that of Borys of Ebe.

The creature is later slain by the combined efforts of Borys of Ebe, Kalak of Tyr, and Hamanu of Urik. With the loss of Kalidnay, the levy to keep Rajaat imprisoned becomes a firm 1,000 slaves from the seven remaining sorcerer-kings.

- Desert's Slumber: After years of investigation into the death of Nerad, a preserver/psionicist named Korgunard learns of Oronis of Kurn. Though reluctant to have another death on his hands, Oronis gives him the preserver metamorphosis spell-but does not allow him to retain a copy.

Rikus returns the Belt of Kings to Kled, but is told to keep the Scourge. King Andropinis pays an extra 1,000 slaves to make up for Tyr's share of the levy.

- Dragon's Agitation: In an effort to protect Tyr from the Dragon, Sadira seeks out the Pristine Tower and its ancient magic. In return for her pledge to slay the Borys of Ebe the shadow giants of the Pristine Tower transform her into the Sun Wizard, giving her power akin to that of a sorcerer-king. Avoiding Tyr, the Dragon attempts to take his yearly levy from the dwarven city of Kled. In the end he is driven off by Sadira and Rikus bearing his old sword the Scourge. During the battle Neeva gives birth to her mul son Rkard, named for the dwarven king who battled Borys 2,000 year ago.

Free Year 10
- Friend's Agitation: Dregoth returns to New Guistenal from the Outer Planes with aspirations of becoming a god. Unsure of the condition of Athas he sends his templars to the surface to learn the state of the Tyr region, learning too late the events that lead to the death of several fellow Champions. Sadira kills Abalach-Re with the broken tip of the Scourge of Rkard on the Ivory Plain. The sorcerer-queen's body is completely consumed by a black ooze leaking from the broken tip. Rikus of Tyr breaks the Scourge of Rkard a second time, this time in the snout of the Dragon. The sword again issues forth a black ichor that completely consumes Borys of Ebe. Tithian uses the Dark Lens to free Rajaat's substance from the Black Sphere, causing his essence to also be released from the Hollow. After 2,000 years of imprisonment the First Sorcerer is once again free. The result of escaping his prison destroys much of Ur Draxa in a grand explosion. In the ruins of Ur Draxa Rajaat battles his former Champions. Rajaat imprisons Andropinis of Balic in the Black, then grabs the Dark Lens from Tectuktitlay of Draj and crushes the sorcerer-king's skull. The remaining Champions scatter while Sadira steals the Dark Lens and heads for the Ring of Fire. Sadira of Tyr discovers that the key to Rajaat's defeat is his shadow, which gives him substance. Using the Dark Lens, the young Rkard casts a sun spell it magnifying its power ten-fold. The resulting brilliance obliterates Rajaat's shadow and sends his essence back to the Hollow, while his body is boiled away by the heat of the spell. Having been in contact with the Dark Lens as Rkard cast his spell, Tithian becomes mystically connected to the Black and Rajaat's elemental nature. The result is Tithian becoming the Cerulean Storm. Sadira tosses the Dark Lens and the Scourge into the Ring of Fire, placing powerful wards around it so that no one can obtain the artifact and once again free the First Sorcerer. As Rkard's spell lights up the sky, a great earthquake rocks the Tyr Region. The full force of the quake is centered west of the Tablelands beyond the Ringing Mountains. The resulting quake creates the Great Rift, a passage leading to the Crimson Savannah of the Kreen Empire.
