The room has a few knick-knacks here and there, and somewhere in the
corner you see broken chains and handcuffs that are used for torture.  But
most of them are rusty and have collected a lot of dust.  The place is a
small and packed as if it is intended to be used more as a staircase rather
than a storage room.  You are about to leave when you notice that the dirt
on the floor has been recently disturbed.  This strikes you as odd and you
poke around a bit more.
