Lake Ciuto (pronounced see-OOH-toe) is a large body of water in the Arrajan Wilds. A number of rivers feed into Lake Ciuto, carrying water from the surrounding hills. The Nestra River is the only outlet from the lake, eventually leading into the Chaska Sea. There are rumors of powerful aquatic beasts that dwell in the depths of the lake, waiting for opportunities to flex their true strength when unhindered by the anti-magic fields.
Some of the routes of the Steel Roads lie under Lake Ciuto. The remains of the bridges that once held the rails can still be seen beneath the waves.
