I'm at level 13 on the Old Nua maze and there is a door that I can't pass.
It requires a password that a ghost is supposed to give me but the ghost doesn't want to speak to me.

I don't want to use console cheats as recommended elsewhere.

I also don't speak Engwathian, but I heard that I'll learn it later in the game and I'm not sure if it is required here.

**How can I unlock this door in a legitimate way?**
