Already Undone for You: In the Durlag's Tower area. Even though adventurers (a few still living, but mostly dead) have gone in before you and have gotten to a certain point themselves, all of the tests, traps, and enemies are intact when your party travels through it. Even Durlag's ghost states that you are the first to have ever gotten that far, even though two other adventurers (Clair and Dalton) can be found in the last two dungeon areas. The ghost is standing close to the only staircase leading up or down from this area, so how did he miss seeing them? One of them handwaves it by saying they took another route which has now collapsed, although you see no sign of any other passages, collapsed or otherwise, anywhere.
Bilingual Bonus: Some tougher werewolves are named "Loup Garou" which is French for "Werewolf".
