The Witstealer Sword is a magical Daemon Weapon forged in the molten heat of desire and cooled in a vat of the Chaos God Slaanesh's own blood.[1a]
Thus did the Dark Prince think to arm his champion, the Keeper of Secrets N'kari, so that he would be fit to defeat the Khornate Bloodthirster Skarbrand.[1a]
Alas, desire has never burned so hot as wrath, and N'kari saw swift defeat. What became of the sword after that point, legend does not tell.[1a]
