Ral's Fury (Free Year -2258)
Infuriated at her lack of progress, Rajaat turns research of the Inner Planes over to Qwith's subordinates. Shortly after an accident of unknown origins opens a gate to the Inner Planes, and obsidian flows across the land for hundreds of miles in each dir ection until the gate is closed by the Seventh Tree. Thousands die in the disaster.
Those killed by obsidian rise as undead through a mysterious power from the Inner Planes. Rajaat's servants arise as the rulers of this land, becoming powerful thinking undead wizards and psionicists. The Dead Lands are born.
