??? is an unknown entity that is waiting/ guarding the gate leading to Dern. They do not have a name and the player can't interact with it like the other NPCs, they only speak to the player during AHC quest. ??? appears to be able to read the player's mind and to reshape reality around them, even simulate events that could happen in the future. They are mostly neutral even though they seem to be "guiding" the player in one way or another.

It should sound dark and mysterious.
