Accepting that Iron Man's interference, although unwanted, had been for the best, Banner departs, unaware of another secret of Stark's: He had sent Banner an e-mail warning Banner about the mutative consequences of the gamma bomb that Banner did not read, meaning that the Hulk's creation was caused by Banner's own frustration and ego preventing him from listening to Stark. When Thor is confronted by the eye of the murdered Uatu, it is revealed that Angela is the daughter of Odin, making her Thor and Loki's sister. She was "killed" as an infant during Asgard's war with the Angels of the Tenth Realm, a crime that resulted in Odin severing the tenth realm from the other nine as "punishment" for their attack. Upon learning this, Thor returns to Asgard to confront his mother Frigga about this. He subsequently travels to the Tenth Realm with Loki to learn more about his sister, unaware that the evil adult future Loki is working behind the scenes. Upon arriving in the Tenth Realm, known as Heven, Thor and young Loki are attacked by Heven's guards. The realm is a predominantly female caste society focused on wealth acquisition with little to no desire for honor. The Queen of Angels convinces Loki to sit down and talk. Meanwhile, the Guardians of the Galaxy and Angela are attacked in warp space by a band of pirates called Warpjackers but Angela abandons the Guardians when the adult Loki telepathically tells her that the portal to Heven is once again open and that she can go home now. Meanwhile, as Thor battles Heven's guards, Angela appears, having been guided to the doorway to Heven by Loki, and prepares to battle Thor. As Thor and Angela battle, the Queen of Angels tells young Loki another shocking secret about Odin. During the times before recorded history, the Angels were protectors of ancient mankind from rogue Asgardians who hunted man for sport. But in reality, Odin hired the Angels to kill the rogues as a secret way of keeping his people in line. As time went on, Odin learned that Asgard's enemies at the time collectively paid the Queen to betray Asgard to weaken it for an invasion. The Queen stole Odin's newborn daughter Aldrif (baby Angela) and "killed" her as compensation. In response, Odin severed the Tenth Realm as punishment, but the Queen convinced her people Odin was a liar who refused to pay his debt and severed her realm from Yggdrasil. Loki tells the Queen that despite the good he has done for Asgard in recent times, his people do not trust him.
