I decided to scout ahead a little for an upcoming side quest, and went to the Great Library, forgeting that the portal back is not working. So I'm stuck, but at least there is plenty to read.
If one of the fine DMs would like to give me a hand getting out, that would be appreciated. And if you want to harrass the captive Dwarf first, I guess I couldn't really blame you.
I'll try to be less forgetful of one way doors in the future.
Thanks.
