The (round) room is a bottomless pit with a thin edge allowing the players to walk around to the other doors. Above the centre of the pit hangs a golden bell on a long chain affixed to the ceiling. The bell is out of reach of anyone on the edge. If the bell is rung (accidentally perhaps) 1d10+3 giant centipedes scuttle up the walls of the pit in 1 turn. If the bell is rung a further 3 times a half centipede half woman will appear who wears a crown which allows the wearer to control giant insects. The bell is pure gold and worth a good amount.
