The mayor informed them that the water was seeming to stop flowing and then retreat back the way it had come, as well as people hearing strange noises coming from the sewer system which may be connected.
Heading down into the sewers the party soon ran into some more of the rat-men that they had encountered when rescuing the Duchess.
The rat-men were quickly dispatched, and Harbeck got to try out his new gun successfully, although the fight was not entirely without incident as Immeral ended up face first in the sewage, which turned out to be somewhat prophetic for how his day was about to go.
Soon the party saw the water acting strangely and every now and again one of them would catch strange whispers warning them to turn back, eventually Immeral saw the water had apparently just stopped and upon further investigation discovered that he was actually standing right in front of a large Gelatinous Cube.
Immeral was able to back away from the cube without getting engulfed, but Harbeck got swallowed up on the cubes next attack which disgorged a strange merman from inside of it to digest its newest morsal.
The merman began attacking the party with spells so Zrayax charged in and Sindorii sent in Bear as backup while the rest took on the cube.
Harbeck was able to break free of the cube but Immeral got absorbed and knocked unconscious just as a second cube arrived from where the party had entered.
Zrayax hurt the merman whilst it was focused on Bear and Harbeck was able to kill the first cube and bring Immeral back to consciousness though not for long as the second cube fell onto the cleric before he could do anything and absorbed him and knocked him back into unconsciousness.
The merman took down Bear before Damakos ended its sorry existence just before Zrayax could get the killing blow, but before he could celebrate the second cube decided he looked like a tastier option than the cleric and absorbed him in and ejected Immeral who succumbed to his wounds and died before any aid could reach him.
Damakos couldnt get out from inside the second cub so it was up to Harbeck once again to slay the creature and save the warlock whilst Zrayax looted the merman of its sweet magical trident.
With all their foes dead the party took stock and did the decent thing...they looted everything, including Immeral still warm corpse, for anything useful before heading back to report in.
