"it's a jewel that tells me where you are when you break it, use it if something dangerous happens. Because if anything happens to you I can't forgive myself."

Felix gave this to you before he disappeared

Or perhaps he came back...just different..he was more muscular,dark skin toned...his soft white hair became black but his eyes remained the same..blue eyes..

You were asleep when you suddenly broke the jewel in your sleep...then...there he is..Felix ...he appeared through your window
