he wants to… put his muzzle where it doesn’t belong?

This one’s entirely a campaign inside joke. Static’s player and I got a bit out of control with rapid fire responses to each other, so our morning seemed to span a ludicrous amount of time to the point of being desynchronized with the other players. This hallway in particular seemed like a mysteriously long walk.
 
Adding to that, around this time our GM released a rough map of the Keep, and mistakenly labelled “Hall H” twice. So the joke became “They went down the wrong H.” This Hall H became a mysterious location that seems to go on forever and lead nowhere.
