Glorantha

From Glorantha Wiki

Glorantha is the equivalent of the Earth in the Gloranthan fantasy setting. Unlike our Earth, however, it is not a round planet orbiting a fixed sun, but an unmoving lozenge. The sky over Glorantha is physically a dome, to which Glorantha's stars are attached. Other celestial bodies move around the dome.

Glorantha is made up of two land masses: the heavily populated Genertela in the north and the more savage Pamaltela in the south, separated by a great ocean scattered with many archipelagos, amongst which are the large island of Jrustela and the thousand East Isles which surround Vithela.
