Empty Hands (джен)

From a prompt on Norsekink: "Pre-Thor AU. Asgardian bodies are full of a type of magic that gives them their "god"-like powers, even if they do not like to acknowledge it as such (this magic power is what Odin removed from Thor when he turned him into a mortal). When someone goes out of their way to save another person's life, the magic in the saved person's body recognizes owing their savior a life-debt. However, this knowledge of this fact has faded from the Asgardian's minds over the centuries. One day Thor, Loki, and the Warriors 4 are sent on a diplomatic mission to a land where the people are quite sensitive to magic. These people, to everyone's surprise, only are willing to deal with Loki. They can detect that Thor and the Warriors owe many, many life-debts to Loki (a knife thrown at the right moment in battle, shielding them with magic, hiding their escape, combating curses, over and over again as they rush into battle without care). The people of this planet figure anyone who owes so many life debts to another has to be careless and incompetent. How do Loki, Thor, and the Warriors react when they learn of this?"
