Large fleets of Granian ships approached the Starship Citadels, a cluster of large island/planetary platforms hovering in space like islands on oceans. They were met by smaller fleets of different ships, ready to stop them. This was the first attack they had faced and it was also their first space battle involving their ships and enemy ships.
With the Granians having a larger fleet and greater numbers, the altercation lasted only a matter of minutes.
It was quite strange, given that most of the attacking ships were trading vessels mounted with unauthorized weapons, manned by incapable creatures who were as good as anxious, mentally unstable teenagers driving cars on a six-lane highway with unstable passengers honking repeatedly.
