The Aradian Universe
Spanning solar systems and thousands of years, the Aradian Empire bloomed from an Earth that had known great trauma and great healing, and flowed across the galaxy, dropping parts of itself on distant planets, growing into strange new societies.
On the planet Zarqon, human societies like Athering and Ixtepan grew. The Terran settlers changed the landscape as it, in turn, changed them, until the idea of being Terran was no more than a myth.
They forgot their past, where they had come from...but a mother never forgets her children, and the Aradian Empire had never forgotten them.
