Systems breakdown
The underground pipeworks below the city of Sarbreenar have been neglected for too long. While the invaders were in occupation of the northern part of the city nothing could be done to maintain them and the infestation of Chokers, and their hybrids, seriously damaged the carefully laid brickwork of Sir Diggit Morninglight and his specialist crew. Careless adventurers casting Fireballs underground made matters worse.
The sewers in the northern half of the city hit a critical phase when the relay pumps and the main pumping station exploded.
Investigations revealed that the flush of water from the Mill Beck, The Mill Stream and the Elvenblood River had slowed to such an extent that the sewers had "sludged up" (a technical term).
Parties of explorers went upstream and cleared the blockages but it will be a long time before the city recovers. Most of the foreign embassy buildings have been abandoned and the ambassadors have left. The streets are still awash with mud and excrement and many of the sewers still lay broken open. Few people are staying in the northern sector by choice. Once this was the most desirable area in the city to live but now it is a scene of desolation.
