[sblock=Dekana]OOC: I'm actually in the process of converting Seven Swords of Sin (the module that this portion of the dungeon and the one from The Cake is a Lie) into a zork-style adventure game. It's a work in progress.[/sblock]
During the wait, Tesla discovers a few of the books in the library might be particularly valuable if taken as a whole. Individually, many of the old books are only worth, at most, ten gold each. However, the complete collection, if you could find a buyer, would easily sell for 1,000 gp or more to a collector in Istivin.
In addition, one of the tomes deals with a collection of weapons called the "Seven Swords of Sin." The book seems, in some way, related to the martial disciplines, but it's difficult to determine what exactly without a thorough examination (taking 1d4 days per intelligence check with a DC of 20).
Supposing everyone waits for the reset, resets the dungeon door, and then starts back in... where to next?
