Circle of Twelve
The Circle of Twelve is a group of powerful magicians who lived in Ancient Neopia, featured in NeoQuest I. Xantan was the leader, and the rest of the group include Jahbal, Kreai, Gors, Rollay Scaleback, Archmagus of Roo, the 5 guardians (Fire, Ice, Shock, Spectral, and Life magic), and Faleinn. They used to be good, but eventually became evil when Jahbal grew mad with power.
Xantan was exiled by the Circle Of Twelve, with most of his power stripped away. He has, since then, made a cave near Neopia City his home.
Being Mad, Jahbal decided to start a war against all others. Some of Empire's cities fell... others stood up to face Jahbal. So did the city of Kal Panning, and it's leader Faelinn.
Eventually, Jahbal defeated Kal Panning's defenders, and turned the city's population into zombies. The other members of the Circle seen the error of their ways (and who they were allying themselves with), and decided to get rid of Jahbal. Jahbal, however made spyed on the Council members, and decided to flee to the Two Rings Castle.
The group of wizards decided not to hunt Jahbal down, for noone knew what arterfacts of power there were in his castle - and cast a sealing spell on the entire Two Rings Range. Nothing is supposed to make it throught that barrier - and at that, they settled.
Somehow, Jahbal has found a way to break through the barrier. Although he himself could never pass the barrier, his magic reached out to the outside world, and created monsters. The monsters, in turn, were ordered to hunt down The Empire's leaders - disabling the empire. Many fell, far more suffered; the seeds of destruction were sown.
They were finally defeated in the NeoQuest I gmae when the NeoQuest Hero defeated them and restored Neopia and made it peaceful.
