Military action
The remnants of the elvish people join with a frightful ally.
After over 80 years of merciless hunting by all other races, the elves were in a horrible position. Almost all of their elders were slain. The eldest left of their race were barely 200. Their great magics were taken or destroyed and the only place where they were safe was the deepest parts of the Forests of Entreities.
Soon a leader arose from the frightened Elves. An Elf named Rannoch. Rannoch promised the elves that with godly help they would be able to win back their lands and to destroy the other races. The god that had decided to side with the Elves was none other than Brilla. Brilla began giving power to Rannoch in exchange for Rannoch's son Khadzeah being possessed by a part of Brilla named Chaos.
Things would have worked beautifully if it were not for Chaos. After gaining his body he decided to fight against his father and the mortals. Chaos opened gates to the Abyss and summoned great daemon lords to serve him. After much hardship these gates were closed and Chaos was defeated by the heroes, who included Rannoch's Sister Pthalo. Chaos was trapped in a huge gem that became the moon, Krakesh.
