There's still a lot in the room that hasn't been investigated, thinks Bartleby, remembering his initial foray into the room (post 488):
corpse, slab, skeleton, black chain mail, sword, possible shield, wall paintings.
Bartleby muses,"Who wrote the warning note? If we can't detect magic on the place, do we just leave this, or do we investigate? Why were those ones changes (assuming they were), and this corpse was not? These are powerful magics."
Bartleby peers closer at the chain mail, skeleton, slab, sword, and possible shield.
