Its name meaning "He who soars" in the Old Tongue, Mah'alleinir is the war hammer of Perrin Aybara. It is named after Hopper who died the final death in Tel'aran'rhiod shortly before its creation. It measures about four feet long, has a large brick shaped head, a long metal handle, and the imprint of a leaping wolf on the side of its head. It is described as resembling an outsized blacksmith's hammer more than it does a "traditional" warhammer, with a wedge-shaped back in place of the typical armor-piercing spike common on typical warhammer designs.
