Greywater Manor

Greywater Manor is a house upstream and counter-clockwise from the Shattered Temple in the Central District of Sigil. It was owned by a human named Gareth who was slain in the first days of the invasion by the Grand Army of Revolt.

In the cellar of the house is a statue of a grotesque fish-like humanoid working at an anvil with a hammer. Drawing a door on the anvil in chalk causes the statue to create an actual door on the wall. The door leads to a small room with smooth walls that seem to reflect things that are not in the room. On the ceiling of the room is a permanent portal to a long tunnel in a pocket of air in the elemental plane of water.

The house currently belongs to the Dogs of War, a group of adventurers operating in Sigil. It is one of the hubs of their portal triangle.
