Game of Thrones: Conquerer

Greywater Watch, the seat of House Reed, is an enigmatic castle built upon a crannog in the treacherous swamps of the Neck. This unique fortress is notorious for its ability to drift, making it nearly impossible for foes or even ravens to locate it. The eerie waters surrounding the castle teem with fog, and the lack of a maester or knights adds to its haunting isolation.
