Room 4

The room smells moldy and the walls you touch are covered in slime. You can hear the sound of dripping water. The wooden planks your standing on are slimy and slick and you stumble into a crate. Rats scramble squiling from their hiding places knocking you over in their rush. The candle slips from your hand as you hit the floor. The rotted timber beneath you gives way, you, and a few unlucky rats are plumeted into a deep well filled with slimy water. You try to climb out but the walls are to steep and slimy, as the rats scramble to stay above water by climbing upon you. Hope you believe in the after life.
