Thanks!! What is funny is that is exactly where I was going to put it!
You would think that the monk who initiated the building of an intricate library would have at least put a more direct route than through a passageway of ants. A secret tunnel perhaps but not one where he would have to travel through 5 other levels to get to.
The library was built waaaay before the ants moved in. Once upon a time, there probably was a more direct route, but centuries of orcs, giants, crashing flying castles, troglodytes, duergar, earthquakes, dragons, and the odd adventurer have changed things around.
It's like in the Clockwork Academy level...there used to be another way to access the laundry than through the dumbwaiter, but, well, things got smashed.
If you come across any other questions, let us know!
