PIRANHA RUN

During the mid-seventeenth century GUE, due to Morphius' curse, the Northern River running through the Valley of the Sparrows became infested with piranhas. The primary breeding pit for these accursed fish was a stretch known as the Piranha Run, which was situated east of the mountain pass entering the valley and north of the Northern River Lighthouse.
