Brokilon Forest, also known as the Sea of Trees, is a vast, ancient woodland realm forming an autonomous pocket between Cintra, Verden, and Brugge. It is the last remaining sovereign sanctuary of the Dryads, ruled by Queen Eithné. The forest is fiercely protected, with dryad archers executing any human trespasser on sight. Characterized by colossal, magical trees like the Duén Canell, it is a deeply spiritual and dangerous place, historically functioning as the fateful setting where Geralt of Rivia first met a young Princess Ciri.
