So I'm on level 13 of the Endless Paths. There is a door with a couple whispering faces/statues. I've tried saying everything to get past them. Don't know where else I would gain this knowledge... Is this related to having released Maerwald's soul...? Or am I just missing a small key place/item which would help me through this point. Any relevant thoughts/tips/fixes would be appreciated.

Aargh! So frustrating! So you mean to say because I released Maerwald's soul I'm not able to advance in the Endless Paths (past 13) or access certain treasure stashes?! ALL THAT TIME FOR NAUGHT?
