Uldred

Derthsin, later known as Uldred ("He Who Is Made of Dread"), the First Dark One, was the first Dark Lord, the primordial source of all evil in Mir, and the original source of the Taint.

He was once one of the Veoldor, turning against his creator Euir and causing his dark power to give his corruption a physical form, the Taint, which he spread throughout Mir. He whispered to the leaders of Men, who invaded the Beyond in their physical forms, leading to the first of the Bloodspawn. He almost brought around the end of Mir, before he was cast out into the Void by the combined forces of the Dragonbound. He is prophesized to return at Ragnarok and bring around the inevitable end of the world.

Song of Creation
Like all the Veoldor, Derthsin was created by Euir in the sixth tune of the Song of Creation.

Etymology
The name Derthsin is an Aen word for "Death Keeper" or "One Who Finds Company in Death".

The name of Uldred was given to him by the elves, meaning "The Black Foe".

Titles
