How The Fight To Survive and A World Away Relate

So, I understand it might have been a little unclear of how The Fight To Survive and the sequel The Fight To Survive: A World Away were related. They did have very similar story lines, but there was little else. My next installment in the series is a prequel about Synca from the original, so it's easy to see how it relates. But what about the second? Well, in the epilogue I show Star and Vega standing at the bridge between N. America and Asia. Then I say that eventually another fight to survive will take place there. What this implies is that Star is Storm's ancestor and Vega is Synca's. Hope this helps clear things up :)
