If We Collided

What if worlds really did collide? What if we met between the stars and within the fire? If the bonds that tied us were family alliance and honour, could we set aside our differences and let go of old grudges? Would the game we've played together all our lives be our salvation or downfall?
Would our existence together resurrect old rivals and bring about new enemies?
You are my starry nemesis and I am your fiery princess. It will take everything our family's have to hold on to the happy endings they've found; and us. Will it be enough this time?
This is the story, dear readers, that answers the question you have all been asking:
What would happen, if we collided?
