Pretty sure Khemia is before Intera since the human MC is still on Earth negotiating communication and peace arrangements between Earth and Adastra while Intera is clearly after the human MC gets back from his return mission to Earth
You just made absolutely no sense lol. You're contradicting yourself in every single sentence of that statement. Interea is during the trip around Adastra that Amicus promised to the human. It is between the nine months they had before leaving to uplift Earth.
I made a mistake and already admitted to it when another person called me out on it months ago... There's no reason for you to be calling me out in the ridiculing tone that you did. I have nothing else to say to you
