The Skull Crusher is an amazingly large, and powerful weapon. The Warhammer was created in a fire, magically fueled by the Wizard, Dorach Gusal, and was forged by the great weaponsmith, Hilbongard Rolamus. The steel is magically hardened and the weight of the weapon is amazingly light, which makes for more powerful swings and deadly blows. The Warhammer was to be put on display for a festival, but thieves got it first. The Skull Crusher still travels Tamriel in search of its creators. —Yagrum Bagarn, Tamrielic Lore

This warhammer is located in the Forgotten Vaults of Anudnabia, Forge of Hilbongard, which can only be accessed via the Omaren Ancestral Tomb (east of Sadrith Mora), in an enchanted chest hovering above the lava pool. It is found during an Oracle's Quest for the Imperial Cult.
