The
Wolf Blade was a massive dull black
chainsword, that lay forgotten and nameless in the depths of
The Order's fortress
Aldurukh on
Caliban, until it was found by the
Primarch Lion El'Jonson sometime before he joined the
Great Crusade.
Though it was already ancient by the time the Lion discovered the chainsword, only he was capable of wielding it and the Primarch claimed it was if the Wolf Blade had been waiting for him to seize it. Afterwards, the chainsword became a part of the Primarch's armoury and in the Lion's hands the Wolf Blade 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 and the Primarch would later make use of its lethal silver runic teeth in the
Horus Heresy.
