Nie'Zaub, the Warm Hand of the Present

Before the Aldruan invasion, the Elves of Einherjar had a Creator who held the magic of the powerful race in check, keeping a sort of status quo while also maintaining the mild climate and gentle environment of the Elven lands. Nie'Zaub was a patron of especially the Fire and Witch Elves, whose powerful, destructive magic schools were safe to their surroundings thanks to him. Nie'Zaub also assisted in creating the Elves to begin with.

Characteristics
Little is known to the scholars of Ardalore about his characteristics, seeing as he does not actively involve himself anymore, and all the libraries and shrines were destroyed by the Aldruans.

Personality
Same as with the characteristics. He's probably off to some self-made island, enjoying a pineapple with straw in a sun chair. Or something.
