Ahzidal

Ahzidal is one of the most powerful Dragon Priests found on Solstheim. His name translates to "Bitter-Destroyer". He is also the first great Nordic enchanter and first Man to master Elven methods of arcane magic.

History
He grew up in Atmoran city of Saarthal during Merethic Era. He had special aptitude for magic and learned from his tutors. After growing up, he surpassed them all. Since he had nothing more to learn in Saarthal, he left his wife and child to learn from Elven masters.

Several years after, he returned to Saarthal only to find his hometown sacked by the Snow Elves. In his rage and grief, he took the name of Ahzidal, meaning "embittered destroyed", and swore to exact terrible vengeance against the Mer.

In his travels, he learned much. By the Dwemer, he learned seven natures of metal and how to harmonize them. From the Ayleids, the ancient runes and dawn-magic. He sought the knowledge of Snow Elves, Chimer and Altmer, taking what he could from each, just to later use that knowledge against them.

After learning of Ysgramor's arrival to Mereth, he immediately sought them out and offered all his knowledge to the Five Hundred Companions. They and their gear, imbued with powerful enchantments, have decimated the Elves in Saarthal and would end the dominion of Elves in Skyrim.

In his lust for power and knowledge, what Man and Mer had, was not enough, and he fell into insanity. He sought out the knowledge of the dragon-runes, which led him into the Dragon Cult. Even this was not enough, so he soon turned his attention towards planes of Oblivion, and came under a thrall of Hermaeus Mora, Daedric prince of Fate and Knowledge.

Ahzidal finally lost himself, falling under his own pursuit of perfection. He fled to Solstheim, only to be sealed by the Dragon Cult in depths of Kolbjorn Barrow with last of his Relics.
