The Rekachka is a small river on Philosopher's Island, in the Lovian State of Seven. In total, its length is less than half a mile. The source of the river is The Tarn, a lake in the center of the island. It flows trough Abraham Park and the village of Novosevensk and its mouth is the Bay of Estonia there. The river has carved out a steep valley between the Confucius Hill and Arthur's Seat, the two highest peaks in the State. The Rekachka is the island's longest river but also the longest of the whole State of Seven.
