4Best: Crookback Bog
Crookback Bog isn’t a pleasant place, visually-speaking.
It’s deep in the Velen swamps, and Geralt hates being in the swamps longer than absolutely necessary.
However, Crookback Bog is one of the most important locations in Velen, story-wise.
It mostly consists of empty, and dusty buildings no-one lives in.
