*TRIGGER WARNING* Mentions of suicide, self harm, rape and sexual assault! Child of Hades, heed the call. You'll return to those castle halls. Lose that which you love more than any. The First will deem when you're ready. If betrayal strikes your friend, Then his Risen soul shall meet it's end. No demigods have ever been born in Ireland, and no one knows why. Two years have passed since the Giant War, and Camp Half Blood has changed with the time. Relations with the Roman demigods has mended and the two groups get along better than they ever have, bringing a time of peace with them. That is, as much peace as demigods can have. But another prophecy is found and looms over Nico di Angelo's head as he is thrust into the life of a certain irish criminal mastermind, or rather juvenile genius as he prefers to be called. The peace that the demigods have enjoyed may finally be shattered as two very different worlds are brought crashing together by an ancient power. Author's Note: First, I obviously don't own the characters or the worlds. Those belong to Rick Riordan and Eion Colfer. Second, when I first started this fanfiction years ago, Trials of Apollo and Fowl Twins didn't exist yet. So the events in those series won't affect the events in this fanfiction.
