After the encounter with the shadow, I found a very long hallway. Descending into it led to level 2 (unsurprisingly). I happened to be right next to a clump, who didn't give a crap about me.
Not far from it, blood. Black blood. Smiler blood. Clumps don't normally attack smilers, so this was odd. The strangest part about it was the blood was recent. The smiler died very recently. More blood seemed to be dragged away, possibly leading to the body.
Should I investigate, or should I just leave?
