A small lake hidden deep in the Sea of Trees, west of the Astralwood, the Lake of Telyth is fed by the Ashwater River. Archdruids from the Astralwood Enclave regularly make pilgrimages to this place, as it's air is suffuse with divinatory and conjurative magic. The lake is thought to be a border between the Material Realm and the Astral Border plane, and it's waters are often read to make predictions and prophecies.
Given the lake's importance as a religious place and crescent-like shape, it has been named after Telyth, the great goddess of the moon.
