Oddworld is the planet where the Oddworld series takes place. The only known named continent is Mudos, Mudos is the home of the Mudokons. Mudos also hosts many locations such as RuptureFarms, SoulStorm Brewery and Magog Motors.
Oddworld is said to be seven times the size of planet Earth.
There are many continents on Oddworld, however in the entire series only small sections of Mudos have been seen. Two main areas of Mudos have been seen, Western Mudos (as seen in Stranger's Wrath) and Eastern Mudos (as seen in the rest of the series). The continent appears to be culturally diverse in terms of both industrial and native species, in eastern Mudos the industrial facilities encountered are much larger and possibly more advanced than those seen in Western Mudos, however, Western Mudos displays a number of industrial settlements inhabited by Clakkerz as well as other settlements inhabited by the Outlaws.
The environment on Mudos (as well as the surrounding area) is at great risk due to foreign settlers. The terrain [besides the flora] is quite rough and jagged. Mudos was originally home to just a few Native species such as the Grubb tribe and the Mudokon civilization. But foreigners [unknown where they came from], arrived and quickly set up an industrial society, wiping out many species and putting others at risk.
