    For the next four thousand years a succession of dragon empires dominate central Merrouroboros. Notable among these empires is the Demesne of Atranjikhera, ruled by the desert landwyrm Argissthilliax. The wasteland empires's rule was harsh.

    While the empires of dragonkind waxed and waned, the giant tribes united once again and spread to cover most of northeastern Merrouroboros. The Colossal Kingdom as it comes to be known is divided into several regions, one for each jotunbrud tribe, Vilmos, Nicias, Ruk, Ottar, Masud, Obadai, Dunmore, and Lanaxis. Voninheim is constructed as the Ostorian capital. »
