The Nestra River (pronounced NESS-trah) is a major river that begins in the Arrajan Wilds, flowing west from Lake Ciuto until it reaches the eastern shores of the Chaska Sea. As the only outlet from Lake Ciuto, the Nestra River is an important route for trade and travel for people living in the Wilds. Though the river is largely no more or less dangerous than any others nearby, rumors have persisted of undead that wait in the murky river depths for passing ships to sabotage and sink.
