Ghoul King's Blade
After slaying many a traveler, the Ghoul King was at last dethroned by an adventurer in search of hidden nephalem artifacts. The monster's sword vanished after the fatal encounter, but it was recently discovered tangled in the roots of a sickly tree in the Festering Woods. The wicked blade still shares its late master's hunger for living flesh.
