Binah is a powerful and sadistic individual committed to her violent duties as an Arbiter of The Head. She describes herself as someone who found a thrill in death and destruction where nothing else had ever managed to impress her, and therefore enacts brutality with both delight and satisfaction.

She wears a modified version of the Patron Librarian uniform: a black coat with a golden trim and fur on its shoulder similar to her Arbiter coat.

She also has a beauty mark next to her left eye, and wears two rectangular golden earrings in place of the one in her Arbiter outfit. In combat, she wears her Arbiter outfit: a completely black fur cape with a straight overcoat underneath, with the only color being the golden trims of their hexagonal patterns.
