Lone Wolf/WMG

The Ancient King buried in the Graveyard on the Ancients was an evil Rival to the Darklords who lost to them.
In the first book; if you screw around with his bones and fail at certain skills; a portal opens that sucks you into Naar's Dark World; a Fate Worse Than Death that ends the game. However, if you have a Vordak gem, the bones and the gem destroy each other.
 * This King was an ancient evil similar to the Deathlord, but he lost favor to Naar over the Darklords. Imprisoned, he can still send graverobbers to Naar for some respite for punishment of not living up to Naar's expectations; but he isn't allowed to touch Naar's current champions. If Lone Wolf has a Vordak Gem; the King destroys it out of his hatred for his rivals. This, however, breaches the rules, and Naar eradicates him.
