Twenty years after the Second Great War, Rigasia ramped up their timeline exploration program. Among other people's they found the anagusi, they they originally mistook for uncivilized cave people.

A total failure to communicate and the actions of the unregulated explorers, both army and ex-convicts looking to buy off their prison time resulted in a fast escalation, and the anagusi domain of Kesizma invaded the rigasian timeline through portals in the three rigasian zones.

The first attack was neutralized by Rigasian bombings of the anagusi keeping their portals stable, killing both civilian and neutral (medical) personnel, as well as unleashing a portal event, all of which are considered by the anagusi to be war crimes.
