A planet of fire and ice, Fenris orbits its sun once every 3-4 Terran years. During the summer months volcanoes erupt, burning great areas with lava flows and churning the seas, spreading great floods and tidal waves. As the planet enters its long winter, the temperature drops so far that most of it actually ices over, giving the planet the appearance of a snowball from orbit.[Needs Citation]
Apart from a single area of the planet that is permanently land-locked, Fenris is a world of shifting geography and mostly oceans. Numerous asteroid strikes, mutable coastlines and even swiftly risen or sunk island masses have resulted in the population becoming one of largely nomadic barbarian tribes. The tribes constantly seek secure territory, and as a result skirmishes and feuds over land between rival tribes are common. The people are hardened to the changes in temperature and extremes, and so is the fauna. The only continent that remains constant is Asaheim, standing on top of the crest of the world. During the summer, it is covered in lava and magma flows, but is habitable during the winter.[Needs Citation]
It is located relatively close to the Eye of Terror. The central sea of Fenris is the Savage Sea, home to most of the planet's wildlife, most of which are vicious sea creatures. Nonetheless the sea provides most of the planet's inhabitants with their food.
- Assaheim — The only stable continent on Fenris, located on its northern pole. Here there are many unique creatures not seen elsewhere on the world such as bears, elks, mastodons, ice trolls, shapeshifting dopplegangrels, and ice wyrms. Asaheim is surrounded by cliffs thousands of feet high, separating it from the rest of the planet. The tribesmen of Fenris consider it the land of the Gods.
- Iron Isles
- The Fang
- Syrtyr's Door — A volcanic cavern with mystical properties, considered by the people of Fenris to be the door to the Underverse.
Flora and Fauna
Because of its harsh conditions, there is little native plant life on Fenris.[Needs Citation] Many studies have concluded that Fenrisian animals are the most dangerous on any planet, even more so than those on Catachan.[Needs Citation]

The population of Fenris is small, yet hardy and tough. Fenrisians are born warriors from cradle to grave, battling not only the planetary conditions but also each other. Land is the most precious commodity of the planet, and as a result tribes frequently clash with one another for its control. Tribal fighting escalates during the Time of Ice and Fire when new landmasses can rise from the ocean. But despite these hardships, the Fenrisians consider themselves blessed, for they have a chance to join the "Dwellers Above the Clouds", the Space Wolves. The Space Wolves carefully watch their tribal brethren, but never appear openly among them. To Fenrisians the Space Wolves are known as the Sky Warriors and have a mythical status.
From a Fenrisian perspective, prospective candidates are mainly chosen from young warriors who fall in battle with grievous wounds, or perform prodigious feats of arms. These youths are taken from their tribes, and their wounds are treated if necessary, and taken to The Fang to train as Aspirants in camps scattered around Asaheim. Apart from the aspirants, the only normal permanent human inhabitants of Asaheim are the Kaerls, the Space Wolves' Chapter Serfs, who also serve as the planet's Planetary Defense Force.[Needs Citation]
