This is a silly thing, just something to throw out there.
It's always interested me that there are at least 1155 known keys to the Corprusarium dungeon and Tel Fyr and yet we can only find 8 of them in game! Has anyone ever considered expanding the dungeon to house a thousand more locks? I think that could make for a pretty interesting game expansion with traps and dangers.
That sounds like fun. Notice that "terrors" are kept separate from the corprus inmates...
If the artifacts he keeps upstairs are any indication... there could be some truly powerful loot down there...
This could be an excuse for someone who wants to create an extensive dungeon dive.
