Return of Xoriat
The Soul Blade is one of thirteen similar magic weapons crafted by Karrnath during the Last War. It was designed to give Karrnathi warlords great advantage while also ensuring their loyalty to king and crown through necromantic and arcane means. This particular sword was captured when the Karrnathi Warlord Vorik Thul fell to Brelish forces.
The sword was returned to Breland and was placed in a Dark Lantern vault until it was stolen by Lucan Stellos for unknown reasons. Lucan became possessed by the sword and attempted to return it to Karrnath. He was eventually apprehended by Dve Kulaki, Charles Pliney Finley and Drago . Drago returned the sword to Thul and Thul was reinstated as a Warlord.
