Overview

Oerth's southern pole appears to have a region that resembles High Boros in climate. This land is reportedly very small and might not be a true land at all. but a thin cap of ice that encompasses several mountainous islands. It is interesting that of the six reputable sources for information on this little-known region, usually named Polaria, four claim nothing lies here at all except mountainous islands of ice or rock in a gray, frigid sea. However, those explorers were present only during the long days of the southern hemisphere's summer (our winter). The ice cap may have vanished during that time, leaving only icebergs drifting among the true islands. The other two exploring parties each stayed over for a long period of time on one true island, and they both report the rapid formation of thick ice over the sea once the sun sets and the long night of winter begins (see Exile from Aerdy, by Sonderrako of Rauxes, and Two Years' Record of the Hidden Sea, by anonymous, in the Guild library). Measurements by the reclusive Savant-Sage suggest that all of Polaria lies below 80 degrees south latitude.
