When Percy Jackson finds out that he needs to go back in time to keep the history of Camelot on track, things get messy.....

Merlin is having nightmares, uncontrollable nightmares that allow him no sleep. He finds himself only able to rest when sir Lancelot is with him. All Much to Arthur's concern. Story based mostly in Arthur's POV

After allowing Gwaine to choose the accomidation, Arthur, Merlin and the knights wake up in a strange pit with no doors, no windows and no way out. But the pit is the least of their problems as they begin to realise they are caught up in something much worse, a game where angels are tested to their limits.

At the age of fourteen, Prince Merlin Ambrosius had fled his kingdom Nelthon due to an attack by Merlin's uncle, Gelmand, with his mother and his friend/knight. Nine years later, three if Merlin's knights come to Camelot seeking help. Will Arthur help them take back their kingdom? And if so, can Merlin do it without revealing who he is to the knights and Arthur? (I do not own Merlin)
