CokolKhan asked Eoghan about fish people who attacked his druidic circle. They killed the entire circle except Coko.
"These", said Eoghan, "These aquatic looking monsters are called "Deep Dregs" - humans mutated into fish people. They are said to have captured the druids and forced them to drink a sludgy, green-black liquid as they were marching them into the (contaminated) Drann river. It is said the druids started growing fins and gills as they entered the water.
The fish people serve a creature called The Duchess. Some of them hang out in the sewers near the city cistern, which, as all you Drakkenheim folk know, opens into Slaughterstone Square.
Coco also expressed an unnatural interest in the ability to wild shape into a contaminated creature, but this:
Requires study that are against all druidic beliefs. Oscar Yoren knows a lot about delerium and other creepy stuff.
- Requires one to chose a single monstrous form.
- You'll pay the price for changing into this forms.... like contamination each time you do it.
- That sums up Coco's revenge quest and has some tie ins to the overall arc.
