The Ancient Wall (Japanese: 聖戦の壁, Seisen no Kabe) is a landmark in Xenoblade Chronicles 2. It is located at the northernmost part of the Central Plain of Temperantia, between the Aegishammer and the Ruined Chapel of Danafas. Coming to this location with Elma, Mòrag, and Brighid in the party is necessary to unlock Elma's level 3 "Keen Eye" Field Skill.
