Mysterious interlopers from another world.
The mirror world the Tai Mora live in has been dying for a long time. Ever since, they have tried to get to Raisa Prime in order to survive.
Kirana's campaign[]
Kirana Javia, Kai of the Tai Mora, conquered every other country in that world and forced conscription into her army. In her brutal campaign, which she began when she was no older than 20, about half of the people in that world died. She quelled a rebellion led by, among others, Nava Sona, but not before they were able to hide omajista children across many worlds.
Kirana has long worked to conquer Raisa Prime and seize control of its temples in order to ensure that no one else can displace the Tai Mora there.
