Moor (Dark Sun)

"Let's skip to the GOOD part" - Moor before leapfrogging across time to the era of Dark Sun.

At a Glance
Having foreseen the destruction of the mortal plane in the not-too-distant future, Moor began siphoning magic from powerful Deva and Tiefling magics in preparation for the coming apocalypse. Crafting a ritual to transport himself across time, Moor succeeded in bypassing the great solar calamity and with his full strength established himself as the ruler of the ruined world.

Dark Sun
Moor was killed in the cataclysmic battle of Harakkis when a group of adventurers travelled from the past to save the future.
