In ''Terranigma'', the planet is portrayed as a hollow sphere (though the map in the game is mathematically a [[torus]]) that has both an external and internal face.<ref>{{cite video game |title=Terranigma |developer=[[Quintet (company)|Quintet Co., Ltd]] |publisher=[[Nintendo of Europe]] |date=December 19, 1996 |quote=The planet possessed two souls. An external face and an internal face. Lightside and Darkside.}}</ref> Since the beginning of the Earth, the external Lightside, the surface world, stood for growth whereas the internal Darkside, the underworld, represented decline.<ref name="opening">{{cite video game |title=Tenchi Sōzō |developer=[[Quintet (company)|Quintet Co., Ltd]] |publisher=[[Enix|Enix Corporation]] |date=October 20, 1995 |language=ja |quote=この星が生まれてからの46億年という年月は・・・大いなる二つの意志によって進化と衰退をくり返している。ライトサイドの意志で新たな生命が生まれ・・・ダークサイドの意志で氷河期が訪れる・・・ライトサイドの意志で道具を使う生命が生まれ、新たな技術が次々と作られていく・・・ダークサイドの意志によってひずみが生まれ、その犠牲者が出る・・・人類はその二つの意志をそれぞれ「神」と「悪魔」という名で呼んだ・・・ / 4.6 billion years after the planet was born, evolution and decline repeat by reason of two great wills. At the will of the Lightside, new life is born. At the will of the Darkside, ice ages come. At the will of the Lightside, life using tools are born, and new technologies are developed one after another. At the will of the Darkside, wrongdoing is born, and it claims its victims. Humanity comes to call these two wills by the names "God" and "Devil".}}</ref> Over the course of [[Age of Earth|billions of years]], these two forces came to be called God and Devil.<ref name="opening" /> Regardless of this inner antagonism, rapid progress took root and primitive life forms evolved to plants, animals, and humans. Technology and industry further expanded civilization, but the fight between God and the Devil was still taking place, more fiercely than ever. The conflict culminated in a final battle in [[Antarctica]], on the surface world, but neither of the two forces was victorious. The continents of the surface world submerged into the sea and the underworld was sealed away.
