Four, rivaling overlords are defending their castles from what seems to be an endless horde of zombies. Thousands of zombies are sent by the Death God - the last Necromancer - and the only way for one to truly survive is to wipe out all of the zombies in his or her region. Naturally, when one survives, the other three will immediately perish.
The four unlucky kings and queens of their respective areas were King Wolf - an UNO Wizard, Lord Savage- an UNO Tamer, Celestial Queen - an UNO Warrior, and Silent Emperor - an UNO Rogue. As they prepared for war, zombies from the distance began to appear in troves.
A horde of zombies emerged and charged towards the four castles, splitting away to 28 different zombie groups of which 7 groups moved towards each castle.
