Monstrous Kingdoms

The Monstrous Kingdoms is an informal term referring to the powerful, non-human inhabitants of eastern Hokkaido. While the majority of these creatures are oni, bakemono, giants, and tengu, there are many, many other kinds of evil and chaos associated with this loose grouping of powers.

In theory, the Monstrous Kingdoms could overwhelm and severely deplete if not destroy the human kingdom of Oyashima if all of their forces were united and sent out to pillage and destroy. In practice, greed, stupidity, internal rivalries and other problems have prevented this from happening, but a strong enough leader could create a real threat to Oyashima as a whole.

The year 510 saw the last serious rising of the Monstrous Kingdoms, but there have been several other uprisings, including one in 878 which destroyed all of Sapporo before it was routed by forces from Honshu.
