Synopsis for "Thor & Loki: The Tenth Realm, Part One of Five"
After the Orb releases the Eye onto the Avengers, Thor sees his Original Sin - Angela is Odin's daughter, and therefore the sister of Thor and the foster sister of Loki. Angela's origin story is also revealed: a long time ago, Odin had Angela as his daughter. Then, a Tenth Realm, known as Heven, home to a race of Angels, declared war on Asgard. The infant Angela was a presumed casualty. And in his fury, after Asgard emerged victorious, Odin severed Heven from the other realms. But Angela had survived, and was raised in Heven to become a bounty hunter.
Discovering Angela's heritage, Thor heads back to Asgard to ask more about Angela from Frigga. After learning a few more details, he heads with Loki to Heven in order to learn more about their sister.
