Heh, that's actually a failure by 1 point of what was needed. Luckily, Turjan has knowledge nature as well, and succeeded on his check.
After taking in the room, Turjan speaks up, "This appears to be an abandoned troglodyte lair, I can smell their stench from here. I wonder what happened to them? Either case, the room inside is likely to be pretty pungent still, those with a weak constitution constitution probably won't want to enter without holding your breath, least you sick up"
With that, he begins into the room, and grimaces after a few steps in and covers his nose.
(anyone who enters the room more than a few feet will need to give me fortitude saves against Nauseated)
