BLACK MOORS WATERWAYS (SECTION 2) ROOM 17
Room 3 - Cistern cluster
This room is comprised of several smaller chambers, each a house cistern like Room 2. Each of the arms of the cluster has its own well drop and its own privy chute which leads to Level 2.
A troll has made the central collection chamber its lair, having climbed up from Level 2 and broken through the bars in the southeastern cistern. It will attack anyone who enters its territory.
Each of the cistern chambers has a 50% chance to contain an item worth up to 5gp in it (GM’s choice).
