It wasn't easy... especially with such a small data pool to work with. And before the UE attacked Nora there was always the risk that it wouldn't be correct...
But I studied every single detail I could from those first two attacks. The types of colonies Ovan and Angel were, their location relative to the Earth and other celestial bodies at the time of the attack, every possible detail I could.
Revising it to work with other enemies would take time though; the cycle was based around years, not weeks or days. Not that I won't try.
And since you responded I can't edit it! *shakes fist*
