Interdimensional, a starship trilogy

"Princess, good to see you", said vice-admiral Nyathi warmly facing princess Elantra. 


"It's good to see you too vice-admiral", she replied. The royal presence is grateful for your intervention. 


"You are welcome my princess", said vice-admiral Nyathi with a warm smile. 


His face seeming less troubled by the sight of captain Maguire holding hands with princess Elantra. 


"I just wanted to say to the crew, the mission accomplished. All invasion forces have been effectively neutralised. The threat to no longer exists. All starships will therefore set course for the return trip to Earth. Captain you will make sure princess Elantra is returned to her palace before proceeding to Earth. The rest of Deep space fleet sets off immediately for Earth. Vice-admiral Nyathi out". 


The image of vice admiral Nyathi was promptly displaced by the images of the Deep space fleet departing from the planet's atmosphere. 


All is fair
