§ Of Beleriand and Its Realms The Silmarillion

Thus the sons of Fëanor under Maedhros were the lords of East Beleriand, but their people were in that time mostly in the north of the land, and southward they rode only to hunt in the greenwoods. But there Amrod and Amras had their abode, and they came seldom northward while the Siege lasted; and there also other of the Elf-lords would ride at times, even from afar, for the land was wild but very fair. Of these Finrod Felagund came most often, for he had great love of wandering and he came even into Ossiriand, and won the friendship of the Green-elves. But none of the Noldor went ever over Ered Lindon, while their realm lasted; and little news and late came into Beleriand of what passed in the regions of the East.
