My lates two creations, the Praetorian 105D(tm) and Humongous Lens Flare(tm)
Due to the near-total lack of fighterbays on IC ships, sorties with even light hostile ships tend to end badly, with bombers being sortied and driving off the IC fleet. The answer to this is the Praetorian 105D, a stripped-down light carrier capable of supplying, repairing, and housing a single wing of fighters or bombers.
The Praetorian series is extremely fast and cheap, but the earlier models (105D, 108D, and 205NF) are very weak targets, unarmed or nearly so, and in most cases highly volatile due to the weapons and fuel stored onboard for reloading fighters
The Shaula system is not really important in any way, except that it has the most Earth-like conditions of any IC system outside the Core worlds.
