It had lain forgotten and nameless in the depths of The Order's fortress Aldurukh on Caliban, until it was found by the Primarch sometime before he joined the Great Crusade. Though the Wolf Blade was already ancient by the time the Lion discovered the weapon, only he was capable of wielding it and the Primarch claimed it was if the Chainsword had been waiting for him to seize it. Afterwards, the Wolf Blade became a part of the Primarch's armoury and in the Lion's hands, the massive Chainsword became a brutal exterminator, which ended the threat of the corrupt Knights of Lupus on Caliban. When El'Jonson joined the Great Crusade, the Lion Sword became his primary weapon, but he still carried the Wolf Blade with him when he left Caliban. The Primarch would later make use of the Chainsword's lethal teeth in the Horus Heresy.
