“ A slow, stupid creature that crawls onto people and latches onto them, often on feet, hands, and other extremities, numbing down the area and slowly feeding on it. It's easy to avoid while awake, but nearly impossible to remove once attached. Many an adventurer has been forced to hack off an arm or leg after waking with a Stoneleech wrapped around it. Sleep with one eye open! (This idea came from 'Wizard's Rule')”
“ Nearby is a region of many curiously shaped hillocks. Last week a tremendous storm washed one of these half away, revealing a strange shed made of concrete panels. Its long side is aligned east-west, about 4m by 3m and 2.5m high, with a flat roof slightly sloped down to the north . The double doors in the south side have murky glass panels in them, but nothing much can be seen from outside, although it looks a bit like the top of a staircase. Will you dare go inside? What will you find there, and what lies below?”
“ What if a invisible person could see other invisible creatures? All you would need to do to check for nasties hiding around is turn invisible.”
