Much of Barker's writing concerns a time approximately 50,000 years after Tékumel has entered its pocket dimension. Five vast tradition-oriented civilizations occupy a large portion of the northern continent. These five human empires (Livyánu, Mu′ugalavyá, Salarvyá, Tsolyánu, Yán Kór), along with various non-human allies (Ahoggyá, Chíma, Hegléth, Hláka, Hlutrgú, Ninín, Páchi Léi, Pé Chói, Shén, Tinalíya) who are descended from other star faring races, vie to control resources, including other planar "magical powers" and ancient technology, as they vie for survival and supremacy among themselves as well as hostile and other non-human races (Hlǘss, Ssú, Hokún, Mihálli, Nyaggá, Urunén, Vléshga).
