Religious event
The event in which black rain fell upon Nim, turning its rivers black. While it was unknown at the time, this is believed to signal the arrival of the Ohdaufehl in Laminarum.
As Nim had stocked its walls full of any elves who wished for safety and food, it saw the fall of black rain that painted the landscape for weeks. It was considered an omen, assumed to be plague or punishment for heresy at the time, which they would hardly be able to stand after the decades of hardship. Today, it is believed to have signaled the arrival of the Ohdaufehl in Laminarum.
