Search Flymm Cargo for the Beast’s Master
Head over to the Flymm Cargo at the dock in the southern part of the Lower City. Pick the locks of the large metal doors. Defeat the pack of enemies inside and enter into it.
Explore the basement of Flymm Cargo
Inside the building, you will find a hatch on the left side. Interact with this hatch to enter the basement.
Continue south across the room until you reach a large door labeled “Machine Parts Storage” Enter into it and proceed through the “Subaquatic docks” door.
The doors open onto an area with a metal bridge and water. Head to the middle of the metal bridge to meet Redhammer the Deviser.
Deal with Redhammer
When you speak with him, he’ll inquire what you’re doing down here, and you’ll see a submersible in the water. Confront Redhammer about killing one of Umberlee’s servants. You have the option of killing Redhammer right now to revenge Holli.
