Cosmic Echelon

The vast federation of outworld states that formed the Terran Empire smarted under the unjust, evil influence of the Emperor Jrun. Daily, his tax-gatherers swooped down on the member planets, wringing the people dry of money and goods. But away from the decadent shell that Jrun had built up, out among the lonely suns of the Edge, a new power was growing. It had fallen on Kelda, the young star-king of Zandyr to form the union known as the Cosmic Echelon.
A fleet of ships that dared to match the armed might of Imperial Terra. The ultimate weapon belonged to Jrun, a battleship which no power could withstand, and a force that could shatter the bodies of men. Here, you can follow Kelda and his warrior princess, Irrena, through the star-strewn wastes of Space; across the Dark Gap in which the empty wrecks of once proud vessels floated forever, manned by crews long-dead.
And realise as Jrun did, that there are two kinds of laws. Those made by Man himself, which can be broken - and the laws of the Universe, which are inviolate.
