This foul, stinking moat is filled with rotten vegetation and the

gnawed carcasses of all manner of beast, humanoid and otherwise. Raw

sewage floats casually about in large, greasy slicks, and clings to

your clothes and hair. The density and stickiness of the murky soup

makes it difficult to swim and impossible not to swallow some of the

revolting filth. A rusty iron door in the moat floor here leads down

into a forbidding darkness.
