The Tylon River runs from the Tylon Mountains and to the Serpent River east of the Mist Swamps. The upper reach up to the four hundred feat falls of Daiche Canyon flows through densely forested hillsides and verdant valleys. South of the canyon the city of Kratas build the trading colony Daiche. The lower portion flows through the rugged plains were the Human tribes of the Dinganni wander.

Before the Scourge the Tylon River was controlled by the T'skrang House T'kambras, but it was destroyed by House K'tenshin.
