Xantari's Night Below
The small lake known as the Eelhold has been created artificially by a log dam across the south-flowing Oldscutt River, causing water to gradually fill the shallow valley in which the lake now lies. The dam was built nearly 50 years past by the Carman family to regulate river flow and prevent flooding further south, where the Oldscutt meets the Churnett. The waters of the Oldscutt can be rapid in spring, and the dam broke on one famous occasion 17 years ago.
Once a year, for five days, the local population of Haranshire come to the Eelhold to harvest the great eels which grow fat in the placid lake waters.The haul of fat eels is enormous, and the surplus is usually cooked, cut into finger-length chunks, and pickled with vinegar and spices before being bottled and kept for the winter. Eels may also be wood-smoked or preserved in a herb jelly.
A Water Elemental lives here and is compelled to protect the dam by a local Nixie. She was having some trouble with it, but the adventuring party gave her a Ring of Water Elemental Control (through a proxy, the ranger Shiraz), and the crisis has been averted.
