Interdimensional, a starship trilogy

"There is a civil war in the Ketana system. But from our investigations there seems to be more than meets the eye", said admiral Gwangwa. 


"With all due respect admiral, I don't see what a civil war several star systems away has to do with us?". 


"It has everything to do with us. We believe that a faction in the governing authority of the planet Byda, is ready to engage with Earth. But for some reason there seems to be strong opposition from the settlements on it's twin moons". 


"Why not let them simply let them resolve their issues without us getting involved?", quired captain Maguire. 


"We strong believe the civil war is being driven from beyond that star system in preparation for invasion of the planet and it's twin moons". 


"You mean, you suspect alien involvement", suggested captain Maguire. 


"I still don't get what that has got to do with us", insisted captain Maguire.
