Metatron is the only angel that endured through the toxicity of the demonic energy and made it to Nebrion on the day the Demons' Gate opened. She swore to stay and help those that are in need and started wandering the ravaged lands. She trusted the people and gave herself in while they performed questionable experiments on her. As a result, her soul was divided and she became a fallen angel. She still holds compassion against the people of Nebrion but the evil part that was born within her wants to trample and ravage every last inferior being. She suffers from the never ending battle within her soul, but she will not give up until the light shines upon Nebrion once again.
Metatron is an archangel in Judaism and known as the Recording Angel or the Chancellor of Heaven. In Hebrew the name is spelled מטטרון and probably derived from the Latin mētātor: "one who metes out or marks off a place, a divider and fixer of boundaries" or "a measurer". According to Jewish apocrypha, Metatron is the name Enoch received after his transformation into an angel.
