i'm losing touch

Harley-for an orphan, always thought he lived a rather normal life. That is until he was discovered to not even be human. Being told that's he's the harbinger of both light and its warmth, and the cold of darkness, was not what he expected to learn as a result of relentless SHIELD studies happening when he took an Ancestry DNA test for class.

or: in which harley keener is the child of summer goddess nanna, and the god of mischief himself, loki.

(i suck at summaries but i promise it's not as simple as an ancestry test telling him he's a god)
