Forlindon
From Tolkien Gateway
After the end of the First Age, the land of Lindon, west of the Blue Mountains, was divided by the great Gulf of Lhûn. The greater northern part was named Forlindon, which means no more than 'North-Lindon' in the Elven-tongue. On its southern shores was the haven of Forlond, while off its northwestern coasts stood the island of Himling, where Maedhros' fortress had once stood.
