A very important thing to mention here is for players who wanted to free Orpheus and have killed Raphael rather than taking his deal. Make sure you bring the Orphic hammer with you to the Morphic Pools because if you forget to, you will not be able to free him.

If that happens to you, since you can't teleport out any longer after that point in the game, you will have to load your save and if the save is not recent, lose hours of game play.
