Mount Gram was one of the peaks adjoining to the Misty Mountains by its southern roots. The mountain was inhabited by a group of Orcs led by their cheif (until the year 2747 of the Third Age), Golfimbul. They terrorized some of the inhabitantsof eastern Eriador which included the Shire.
In TA 2747, the growing troops of goblins from Mount Gram attacked the Shire and so caused the Battle of Greenfields. Those orcs fell in battle against Brandobas Took and their leader Golfimbul was killed by him.
Portrayals in Video gamesEdit
Mount Gram itself is not accessible in The Lord of the Rings Online, but the foot of Mount Gram in the Ettenmoors serves as a home base for the forces of Angmar in the game's player versus monster player area.
