Terca Lumireis (テルカ・リュミレース Teruka Ryumireesu?) is the world in which Tales of Vesperia takes place. There is a substance that suffuses the world called aer, which humans once used as a fuel to operate an ancient technology called blastia. The people live in fear of the hordes of monsters that crawl the earth and rely on the barriers created by blastia to defend themselves. Terca Lumireis is heavily controlled by the Empire, apart from the Guild Union and non-Union guilds, though there has been no emperor or empress for several years prior to the events of the story.
There are six continents on Terca Lumireis: Ilyccia (イリキア Irikia?), Tolbyccia (トルビキア Torubikia?), Desier (デズエール Dezueeru?), Hypionia (ヒピオニア Hipionia?), Weccea (ウェケア Uekea?), and Yurzorea (ユルゾレア Yuruzorea?). The Inner Ocean (内輪の海 Uchiwa no Umi?) is surrounded by the six continents, while the Outer Ocean (外輪の海 Gairin no Umi?) surrounds the six continents.
