Pyro Stick:
From the old undead book:
Deiter Helsnicht was once a great and much feared wizard who was forced to flee from the city of middenheim when it was discovered that he was a Necromancer. From his secret fortress in the Forest of Shadows he slowly built up his strength and plotted his revenge. After decades of preparation his evil plans reached fruition, and the Doom Lord marched forth at the head of a hugh army of undead creatures to attack Middenheim. After a long campaign and many victories he was finally stopped at the Battle of Beeckerhoven by a combined Empire and Kislevite force. The Doom Lord’s body, however, was never found and it is commonly supposed that he escaped on the back of the manticore he rides in battle.
About his sowrd:
Chaos Runesword - This weapon was forged by Grungi Ironheart, a Dwarf Runesmith who was corrupted and led astray by the Chaos Gods.
