Aleyiss San was the crown princess of the San Empire, a highly decorated officer of the High Guard and eventually became its ruler after the death of her insane and tyrannical father, Shineao San. When her father Shineao entered his empire into the Restored Systems Commonwealth, Aleyiss enlisted in the High Guard and became one of its most decorated officers, even getting the chance to meet Dylan Hunt, the restorer of the Commonwealth. Once aboard the Andromeda Ascendant, Dylan struck up a compromise with Kulis; he brought his group of planets into the Commonwealth and he could marry Aleyiss.
