The Elder Scrolls is a fantasy, sandbox, role-playing game series that began a tradition of games based on the principles of "being who you want and doing what you want" that have persisted throughout the series history.
The Elder Scrolls takes place on the planet Nirn on the continent of Tamriel which is divided into several provinces. Little has been mentioned of what other continents lay beyond Tamriel. Nirn has two moons (Masser and Secunda) and numerous races both living and extinct with deep histories and unique cultures. Ten races: Imperial, Nord, Redguard, Breton, Altmer, Bosmer, Dunmer, Orc, Argonian, and Khajiit exist on Tamriel and have been featured in all games so far.
The races of Tamriel recognize nine gods: Akatosh, Arkay, Kynareth, Talos, Stendarr, Dibella, Mara, Julianos, and Zenithar, known as the nine divine. Demon-like beings known as Deadra who dwell on the planes of Oblivion have a strong presence on Nirn and of which seventeen powerful princes are known: Sheogorath, Jyggalag, Sanguine, Clavicus Vile, Mephala, Peryite, Malacath, Hermaeus Mora, Molag Bal, Azura, Boethiah, Hircine, Mehrunes Dagon, Meridia, Namira, Nocturnal, and Vaermina. Their counterpart the Aedra are rarely mentioned and many races have their own deities largely unknown or unrecognized by other races.
Creatures ranging from ogres, unicorns, dragons, hag raven (harpy-like beings), mammoths, giants, mud crabs, cliff racers (pterosaur-like beast), saber cats, trolls, wraiths and other such beasts roam Tamriel, many of which are found in a specific province and no where else. Many illnesses and diseases afflict the inhabitants of Nirn and this includes several variations of vampirism and lycanthropy.
