Sibir is a "kidney-shaped" continent located in the southern hemisphere of the planet Deneva. It is the location of the Sibiran Range. (Decipher RPG module: Worlds) Sibir is also the location of the province of Mallarashtra. (ST - Destiny novel: Lost Souls; TNG novel: Losing the Peace) The Decipher guide describes Sibir as "cold and almost completely uninhabited," indicating Mallarashtra may be its only settlement.
