Formed from alliance between Iobarian humans and several native centaur tribes, Zastel was a region of eastern Iobaria that broke away from the empire in 2602 AR.
In 2654 AR, Iobaria launched the Reclamation Wars to regain control of the breakaway region. By 2686 AR, Zastel had been defeated and returned to Iobarian rule.
