Temple to the Dark God

The Temple to the Dark God was a secret and well hidden temple built in the Colonies, to worship the Master of Jigoku, Daigotsu.

Shadow Dragon Imrisoned
Because the Shadow Dragon was an untrustworthy ally, and because it refused to kill Iweko Seiken before he was chosen as Iweko I's successor, in 1200 the Spider Clan Champion Daigotsu Kanpeki lured the dragon to the Temple. Daigotsu appeared there and imprisoned the Shadow Dragon in the temple.
