A slower, wider river in southeastern Wycendeula, fed by the Shivyll and several minor tributaries. The Lygrone meanders across flat terrain, creating marshland in its lower reaches before emptying into God's Bathtub.
The Lygrone valley shows more signs of ancient habitation than anywhere else on the plains—foundation stones, buried roads, and occasional surface ruins are common. The satyr seem to avoid the area more than geography would explain. Whether this is superstition or something they know that outsiders don't is unclear.
