He is the Son of Elly and Juri.
When he was a apprentice he fought against a jaguar. He fell in the River and hit his head against a Stone, because of that he lost his memories.
Fallen´Angel was found by Snowflake (Schneeflöcken), she helped him and named him Azrael. Both of them, then went to a nearby pack. Spring´Star the alpha of the pack they went, wanted to help Azrael and looked for Azraels home Pack.
She found it and brought him back to the shadowraven Pack. Lilith, his Sister, did say his name, but he didn´t recognized the name. Lilith was sad about that but she showed him the Pack camp. His name is still Fallen´Angel but everyone calls him Azrael.
