Danetian is an artificially constructed Indo-European language. It was created by applying a series of regular sound changes to Proto-Indo-European. The result of this process is a naturalistic conlang with a rich inflectional morphology, and a healthy dose of irregular forms.

The Danetian people, much like their Indo-European ancestors, were horse nomads roaming the Eurasian steppe. They originally inhabited the area around Lake Baikal and the Yenisei River in modern-day Russia. However, due to a series of military conflicts with neighboring Turkic tribes, they were forced to migrate westward in the eighth century CE. After an arduous journey characterized by more military conflicts, they eventually settled in the coastal plains of modern-day Romania and Bulgaria, in the region of Dobrudja.

The core vocabulary of Danetian is inherited from Proto-Indo-European. However, since the Danetian people were in contact with neighboring Turkic tribes for several centuries, the language has borrowed many words from the Turkic languages; these are mainly military words, and words relating to the nomadic way of life. Danetian has also borrowed extensively from Latin, Greek, Arabic, and Persian.
