Tor Gvalchca, the Tower of the Falcon, is a colossal, ancient elven tower constructed from white stone, rising from the highest peak of Undvik island. This monumental structure is the absolute absolute epicenter for the final main story quest of the game. The tower features active magical energy fields, reality-warping portals, and a cosmic nexus point where the Conjunction of the Spheres begins to tear open, serving as the dramatic, apocalyptic stage where Ciri must step through to stop the White Frost.
