Rathlóriel

The later name for the River Ascar, the northernmost of the six rivers that flowed through Ossiriand. Its name was changed after Beren led a force of Laiquendi to defeat a band of the Dwarves of Nogrod on its banks. The Dwarves had sacked the kingdom of Doriath, and with their defeat, the treasuries of Menegroth were emptied into the river. After that time it was known as Goldenbed, or Rathlóriel in Elvish.
