Missing Fish

Marcus gave us this job in session 17
The fish in Lightwash Lake are missing. They think there could be a large Sea Monster of some kind eating all the fish. pays $35k gold.
We learn that a smaller fish the Kandaroo is parasitizing other fish and those fish die after a while of being infested. The medium fish disappeared first from the lake, this is because they have less ability to live with this fish breeding in their gills.
The source of all the Kandaroo is a very large Electric Catfish that seems to have some Spliced soul stuff going on, similar to the Golem with the elemental soul spliced into it.
The Golem was likely spliced by Luminus as there was a Gold circlet attached to its head - which is one of the Finger's Weapons objects.
We killed the catfish and fed all of Greenwarf with it. Losing Aurelius in the process.
