Armaros

Armaros: One of two hundred Watcher Angels said to have left Heaven in pursuit of mortal wives.
Also known as the Grigori, the tale of the Watchers appears in the Book of Enoch as well as in the Jewish Haggadah. In addition to their sins of the flesh, these fallen angels were said to have taught forbidden knowledge to humanity before the Flood. Armaros taught the resolving of enchantments.
