Oni

The Oni are a Funkey Tribe, the only one in the Hidden Realm that is native to that area.

The Great Funkey Wars
The Oni were a tribe living in the Perilous Verge and fighting the forces of the evil King Kahn. Their ruler, King Sidd, worried that the Perilous Verge would be destroyed in the war, and cut it off from the world by releasing a powerful magic called the Gauzian Blur, and destroying all paths leading up to the Verge. When the Funkeys united under King Funkankhamun, the King believed that the Oni and the Perilous Verge were lost to the advancing hordes, and thus the Oni had no contact with the Funkeys for a long time.

Recent History
The Oni are now under the rule of Kane, King Sidd's most trusted accomplice, whom King Sidd left in charge after he went up the highest mountain in Hidden Realm. The Oni and Kane all spend their time training and showing off in the great Oni Dojo.
