Interdimensional, a starship trilogy

"Princess, I know that you can hear me", captain Maguire said . "I know that you are unable to respond due to your concerntration on the battle", said captain Maguire. The live footage on the big screen portrayed an intertangled mass of Bydanian, chaldarian and Drachalian starships, squaring up against each other. Charging at each other, lasers blazing. 


"Space command 's Deep space fleet is coming to land support me. The royal Bydanian fleets are requested to disengage so that the starships of the Deep space fleet can take out both chaldarian and Drachalian fleets in sweeping counter attack". 


"I hear you captain of the starship Sandawana. It is not that easy to disengage without risking incurring losses", replied princess Elantra standing in the middle of the bridge, her entire being glowing with energy. 


"It is not the royal desire that any Bydanian lives should be lost in this conflict", princess Elantra remarked speaking dispassionately.
