The Jeni River is a small tributary of the Tomarsulk River in central Cheliax. It begins in the foothills of the southern Menador Mountains and flows west through the Fields of Chelam to soon join the Travek River to form the Tomarsulk. Near the headwaters of the Jeni, the honeycombed hills have become a haven for runaway slaves who have resisted the Chelish government's strongest efforts to dislodge them. Even the famed archers of House Napaciza could not successfully track them down. The ex-slaves are said to be led by a Chelish noblewoman whose entire family was believed to have been eradicated by House Thrune during the country's civil war.
