The seer Michael, the founder of the Order of the Jedi Bendu, had an older brother with whom he learned of the Force, though they were unaware at first of its light side and dark side. Over time, Michael's brother began using the Force for personal gain, such as power, wealth, and seducing women. This created the distinction between the light side and the dark side, which were termed the Ashla and the Bogan.
Both Michael and his brother amassed a number of followers, with Michael's following the Ashla and his brother following the Bogan. The two brothers eventually fought one another, and Michael killed his brother in combat. His brother's followers continued on, however, as did the dark side, as Michael and his own people founded the Order of the Jedi Bendu.
