Dwarven Hall: 2nd lvl will open later on, when you have the Dwarven Council quest (6th member) = the scrying statue has to show the Axe memorial, then you've got the quest.
No way to fix the source.
Locked room and the girl with the special treatment belong together. Have you got the quest from Corinna to free Penumbra?
Gather both council members: Elf and dwarf = then ask your elven maid again.

How many council members did you retrieve already?
