The Ánova Isthmus is the strip of land connecting the Great Southern Forest to the Southwest and the Kingdom of Pevenath to the Northeast. The Northwest edge of the isthmus is composed primarily of the Broken Mountains, from which the land slopes towards the coastline on the Southeast. The Giant’s Tableland forms the majority of the isthmus landmass.
The isthmus and its surroundings are subject to hot, dry summers, and mild, rainy winters. In the winter, the warm ocean winds blow from the Southeast. As they near the Broken Mountains, the humid winds meet with the cooler Northwest ocean air, and heavy rains cover most of the area. Rinn Town has made excellent use of the volatile climate, cultivating Rinn Valley into the best cropland in the region.
