Interdimensional, a starship trilogy

"Today I saw her majesty, queen Quintara the commander of the sky nations legions, rain down fire on our enemies Qorat, commander of the Tigalash division of rock warriors. The last thing he had seen as he was being knocked to the ground by the irresistible force of the explosion was the enormous ball of flames. In the midst of which was queen Quintara, looking every bit the warrior queen of legend whose gallantry had been spoken of through the ages. 


From his foundation he had grown up on such tales, but this day, he had seen for himself. 


Queen Quintara holding sway up in the air in the midst of bellowing flames. 


"Hail the queen, commander of the winged legions of the sky!", exhorted Qorat and the rest of the rock warriors took up the chant. 


Queen Quintara was in two minds, below on the surface the rock warriors were waiting to be addressed. On the horizon the mighty beating of wings told of the approach of the remaining warriors, she had left skynest with.
