In 938 BCE the San'Shyuum first encountered the Sangheili on Sanghelios who, like the Stoics, believed that Forerunner relics are to be worshipped, not modified. This ideological difference resulted in the Sangheili-San'Shyuum war, in which the Sangheili had a distinct advantage in infantry combat due to superior numbers and troop quality. However, in space combat the San'Shyuum had a great advantage because of their Dreadnought.
