Azrael

Azrael, Throne of Release, was an Elohim who rallied members of the Seventh House to rebel against Heaven. After Lucifer declared that the hierarchy of the Fallen would be restructed, Azrael was named Archduke of the Alabaster Legion, which contained many Slayers and others who remained unaligned in the war. Under Azrael, the Alabaster Legion constructed first Kâsdejâ and then Haven, the latter of which was kept a closely-held secret even from the Morningstar. Such was his dedication to the success of the shadow realm, Azrael sided with Abaddon and Asmodeus in breaking from Lucifer, in exchange for the resources of the two archdukes' in creating Haven.
