The Phoenix found the Moto family had a curse in their bloodline, and anyone of Moto blood drew ill fortune, which they passed to the descendant they bore with the members of other families. Once the notice was spread the Unicorn considered it a Phoenix insult. The Unicorn army invaded the Phoenix lands and laid siege at Kyuden Agasha until they were repelled. The remains of the attackers were pinned in the Mountains of Regret, cut off from the main forces, trapped in Treacherous Pass.
