Notes
- During the White Lady contract there is an examination point to be found outside of the tower at the top of one of the ruins walls. Spending a bit of effort may bring Geralt close enough to look at it, though examining the point yields no commentary or extra information from him whatsoever.
Trivia
- It's likely inspired by the name and history of Zamek Drahim.
