A WikiWarlock and its minion

A WikiWarlock is an elusive, extremely dangerous vandal that uses sneaky and disruptive spells to vandalize and cause havoc. They love to vandalize; but do so discreetly, and with a nefarious purpose. They often use spells to further their unholy purposes, and can even summon up their Doppelgänger to cause huge trouble. It is often, indeed almost always, necessary to evoke a legendary hero to consign these powerful sorcerers to the oblivion they so richly deserve.
