Black Book

This chapter begins with an npc asking for help named Pahom. The first part of this chapter sends you to his salt mill to investigate some worker deaths mysteriously around the salt mill. Nothing tricky about this part, you just need to follow each map node and you will make it to the mill while investigating each area, eventually leading inside the salt storage barn and meeting a mermaid.

The next part has you finding the entrance to the water domain of the demons, leading you through various swampy areas and investigating side paths. Once you make it to Hell's Lake, you will be thrown off your boat by a giant fish and wake up under the lake.

Under the lake, the mermaid will guide you to the entrance of the water domain where you fight the giant fish before heading below. The mermaid will then take you further down towards the last area where the demon resides and he will send you away to figure out what happened to the bandits giving offerings to him.

When you find the bandits in the next area, you will realize that you must figure out a way to resolve the issue. Proceed further to the tavern/pothouse and kill the demon terrorizing this place. Now you must make your way to the watermill to summon the water demon. When you make it there, find the three boards around the area to fix the water wheel inside the main building, turn it on and then make a choice when speaking with the water demon. Whatever you choose to do, this will end the chapter and unlock this achievement.
