The Avengers can't always protect the Earth on their own. So when that happens, a few of our resident demigods swoop in to save the day. Before SHIELD can find them, they disappear. How long will it take for SHIELD to discover who the demigods are, or will something make them reveal themselves first? Not entirely sure how bad the language and violence will get so T to be safe.
