A small stream in western Tangiern where fey activity is unusually high. Travelers report sprites, will-o'-wisps that lead them off the path after dark, and stranger things they will not name. The creek itself seems to move: no two maps place it the same way, and the locals claim it flows to a different valley on different days. They leave bread and a coin at the last fixed landmark before they go looking for it.
The Tangier will give their dead to no inland water, but Feycreek they avoid for a separate reason. This is not haunted water like the elven rivers to the east; whatever lives in it was here first and answers to nothing the Tangier understand, and a will-o'-wisp on the Feycreek is not a lost soul but a thing pretending to be one.
