Sea of Tanismere

The Sea of Tanismere, also Tanismere, was a large freshwater body of water straddling the shared border between Moriga and Vondheide. It covered an area of about 62,000 mi2 (100,000 km2) and had a maximum depth of 213 ft (71 m). It was home to several unique fish, and on its shores were two major cities: Fairwind, the capital of Moriga, and Vondheide's Grauenpass. Both derived much of their commerce from the lake's fish.

The lake was in large part a cause for the region's temperate weather and wet seasons; on average the region received 55 inches of rain annually and an almost equal amount of snow.
