Each game in The Elder Scrolls VI is set on Tamriel, the fictional continent that populates the series universe. It combines elements from pre-medieval reality, such as a strong Roman-like Empire with fantasy medieval tropes. This includes limited technology and widespread magic use. There are also many mythological creatures.
There are a variety of provinces on the continent that are populated by people and popular fantasy humanoid races like elves, orcs, and anthropomorphic creatures. The lore often depicts a hero chosen to defeat an intruder, which is usually a hostile army or malevolent being.
