Arúmil

The last emperor of the Grey Dynasty.

Known to have been especially cruel, and an unusually passionate believer in the principles of racial purity that formed the basis of the Grey Empire's ultra-hierarchical society. Highly intelligent and strategically minded, he sought to learn as much as possible. and had an extensive knowledge of history and an intimate acquaintance with aspects of the arts.

He was a person of contradictions. Ironically enough, contrarily to his belief he himself was not a true pureblood grey elf. He also obsessively hunted down surviving gnomes during his reign, as they ranked lowest in the caste system he so revered, while simultaneously being obsessed with understanding their runes and their effects on reality, the deeper aspects of which eluded his supposedly superior mind.

After his defeat at the hands of the Hero, the empire crumbled, the remnants of the grey bloodline were exterminated and the modern societies of humans, dwarves and elves were established.

Millennia later he came back to life and briefly took over the local world, before being defeated by the Wanderer (now mortal and stripped of his elemental affinity), an army of temporarily reanimated grey elf trees, and Surtur who happened to be passing by after a centuries long journey across different parts of the Worldplane.

Abilities

He is a competent swordsman, and has a firm aim. He is very intelligent, possess some knowledge of runes, and may even have had some understanding of the Souleater's purpose.

His especially strong connection to the element of ether allows him to manipulate souls at will, which means he has direct control over the minds of everyone within a certain distance of his current position (radius depending on his current state of power), and can decrease people's lifeforce directly without the need to physically damage them, or even completely remove it, thereby killing them.

His energy manipulation abilities are beyond even the Wanderer's (in power as well as precision), although he rarely uses them.
