Achei isso no manual Crash 2 (ênfase minha):
On his way home to get her power pack, Crash is suddenly blinded by a flash of light. Next thing he knows, a holographic projection of Cortex is talking to him in an ancient Warp Room!
Cortex tells him about the impending disaster, and urges Crash to help him find the 25 crystals needed to power the only means of survival the Earth has left - the new Cortex Vortex. He explains that an ancient civilization built the Warp Rooms centuries ago, and that their door provide instant access to points all over the world - places hiding the coveted crystals! Of course, Cortex doesn't know that the Earth also contains valuable gems - 42 clear and 5 colored - which may hold the key to his downfall!
Eu não acho que isso seja realmente explicado no jogo (não é exatamente um diálogo pesado), e eu não tenho certeza de como ele se alinha com a sala do Espaço, mas parece que a melhor resposta que temos é.
