Niera is an oblong continent with two large peninsulas, the Ecian Peninsula in the north and the Cariside Peninsula to the east, as well as several smaller peninsulas such as the Minian Peninsula on the north coast and the Yorince Peninsula on the west.
Niera contains several distinct geographic and cultural regions.
Niera has several island chains whose resident nations play a significant role in its politics and economy.
- The Alkemalon Islands, an archipelago in the Selianis Ocean, located off the western coast.
- Sero Villa, a chain of islands south of Niera off the coast of the Cariside Peninsula. Together with the peninsula they enclose the Sea of Blood.
- The Tassicon Islands, located off the northeastern coast across the Carnroll Sea.
Niera was known to northern scholars as South Wollus, but that name has fallen out of use in favor of the local name.
