Tunsiba (pronounced ton-SEE-bah) is a large island in the Chaska Sea, within the territory of the Tirionite colony of Nionegrast. Not far offshore from the mainland, Tunsiba was the first major area of growth within the colony. The old forests of the island have long since been felled, mostly replaced with farms and pastures. Tunsiba is almost entirely under the charter of the Silver Falcon Company, though other Tirionite conglomerates have interests in the island as well.
