The Caerno River (pronounced CARE-no) begins in the foothills of the Karn Andur before flowing north through Erenon into the Phiora Sea. Wide and slow-moving, the river is a major artery for traffic in the slowly repopulating province.
The Caerno River fed Lake Restone, once known as a retreat for the wealthy of Viridia. The lake was artificially created via a dam at Restone, though it was destroyed in Y9975* when the dam was intentionally broken by forces loyal to Sircathe Wriys, the ruler of Wymoor, in order to better access the ruined tempest hall underground beneath the lake. In doing so, they released a massive wave of water that swept through Restone, destroying most of the remaining structures of the city. The artificial reservoir is now functionally gone, a small shadow of its former size. The water unleashed swept downriver, destroying bridges and piers and uprooting trees along the river's path.
