Bezaliel, the Shadow of God, was the 13th Watcher of the 20 leaders of the 200 fallen angels that are mentioned in an ancient work called the Book of Enoch. His name being the Shadow of God due to the fact that he personifies the shadows and shades in creation. Thus it makes him one of the most mysterious angels in all of Creation, with very beings in Heaven and Hell as well knowing his character truly.
His features are all shrouded in just enough shadow that they cannot be made out, no matter what angle he stands at, nor how much light is shone on him. Bezaliel's eyes are in stark contrast to this, at least on occasion, as they flare with bright white lights when under stress. At his side, he carries a sheathed sword which no one has ever seen him draw. On his belt dangles a book on a leather strap, the inside of which no angel has ever set eyes upon. Neither the book nor the sword were present on his fall, and only appeared a few years after, which has caused much speculation among both angels and demons alike.
