Shadowlands Horde was a term first used by the infamous Yogo Junzo in the 12th century. Junzo claimed that he had a dream, a vision in which the diverse creatures of darkness were unified beneath a single leader, and called this army the Shadowlands Horde. He also told that the newest mon of the Shadowlands, a scowling oni, came to him in that dream. Junzo emblazoned the mon in a Battle Standard rallying the minions of the Shadowlands under it, and declared himself as the new leader until the return of the true one. Others simply called it Yogo Junzo's Army.
