Flannaess

Flannaess is one of the four continents of the fictional world of Oerth, home to the Suel and Bakluni people and eventually invaded by the Flan. The other three continents are Hepnomaland, to the south, Aquaria, to the east/west, and an unnamed landmass on the southern hemisphere. None of these are are detailed enough to provide a rival setting, though.
