"It proves to men and women alike, that no other race shares the same blessing. That only those gifted by our shared mother deserves the gift of strength and ultimately... life."
―Flamma Aben some time after discovering the alius
The Alius was an alternative magic source, which was developed by the sacers sometime around 100 B.P. It was originally used to evolve single cells into fully matured Sacers, which accidentally triggered a subrace for the Sacers, known as humans.
