Stuck: Citadel of Dr Cassiopus_Hard

Thanks for the reply.

IS there an exit or any reason to visit that room, then?  I ask because I've explored the room thoroughly (and died repeatedly), and have not found anything there but trolls and ladders.

Please tell me if I'm just not doing it right?  Not looking for any kind of spoiler; a yes or no will do me fine. 

Again, thank you.
