The Citadel Cartographic & Pathfinding Engine
Constructed in the tradition of the Archmaesters of Oldtown, this cartographic engine charts George R.R. Martin's A Song of Ice and Fire universe across Westeros, Essos, the Summer Isles, and the lands Beyond the Wall. Featuring high-precision 10,000 × 8,300 coordinates calibrated against the 600-mile cartographer's scale bar and the canonical 300-mile length of the Wall.
