I saw a considerable Dominic Flandry influence in this regional sourcebook, which is not at all a bad thing.

Three of the four adventures deal with the barbarous Idorians and their scheming Imperial contacts, while the other could drop in to almost any setting. I found the adventure format a little difficult to follow, though a GM with sufficient time to prepare should be able to untangle it all right.

For anyone thinking of picking bits out of here for a different game, it's probably most compatible with Traveller or Space Opera with more thought required for other settings.
