Loki

Loki is the God of Michief, Adoptive Brother of Thor, and Adoptive son of Odin. He was born to Ymir, the first Frost Giant. After being forced to leave Jotunheim, Loki eventually fled from Asgard, to Midgard. He adopted the mortal name Ikol, and soon had to care for Thor's orphaned son, Prumur. Loki, knowing of the imprisonment of his Son, Fenrir, and Grandchildren, Skol and Hati, wrote a book with an ecrypted method for breaking Aesir Magic to free them, under his alias, Loge.
