Hammerfall was formerly one of the largest of the Alliance internment camps. It was attacked and destroyed by Thrall and the Horde in order to free the orcs held captive there. Shortly after the end of the Third War, the Horde re-occupied the ruins of Hammerfall to use as a forward base in the Arathi Highlands. The city is so named in honor to Orgrim Doomhammer, who was killed by a human knight, a lance strike through the back during the camp's liberation.
Orgrim Doomhammer, once the Horde’s Warchief, fell at this historic location. After the Second War, Hammerfall became an internment camp for the leaderless orcs. Now, members of Thrall’s Horde occupy the camp. ( )
The name Hammerfall is taken from the Swedish power metal band with the same name. Blizzard employee Samwise Didier has painted several covers for the band so it is likely to be a tribute to the band as well as to Doomhammer.

Points of Interest
There is a Flight master, an inn, a Mailbox and a few quest keepers inside of Hammerfall. Behind the village is the Horde portal to fight in Arathi Basin. Arathi quest givers and Arathi Basin token vendors are located there.
Hammerfall is under siege from the combined forces of Boulderfist Ogres and Witherbark Trolls of Arathi. In addition to the  quest chain, groups of 5 Witherbark trolls occasionally spawn from the Witherbark Village in the south. They run up the path to Hammerfall's front gate and start attacking the guards. While the guards are capable of staving off each attack, players can also engage the attacking trolls, adding to the sense of threat from the Horde's enemies in the highlands.
