Topic: Mostly Harmless: Ships of the Unkindness of Ravens
There is a particular race of intelligent birds in one of the Coreward systems that knows neither fear nor pity. They are smart enough to know how a modern warship works (in fact, they could probably build one), and given a large enough group, could easily overcome the unlucky crew of an errant ship and steal it, becoming a plague upon the universe.
Fortunately, they're routinely slaughtered to feed the citizens of the Unkindness of Ravens, the other race of intelligent birds in that same Coreward system. (When asked how they could consume fellow sentient beings, the answer is invariably "With salt.")
"Ravens" is a human appellation that stuck within the universal community, seeing the creatures as upscaled, anthropomorphized black birds, whereas the Ravens themselves tend to call members of their species "fellow things that are not to be eaten," and while technically the human name for a flock of ravens is an "unkindness," not a flock, the difference is lost on the Ravens, the universal community, and most humans (with the possible exception of ornithologically trained starship captains).
Their ships have a definite bird motif - outstretched wings, long tail sections, and an annoying tendancy to make a mess on freshly refitted ships - and despite their dated engine technology, the Ravens' ships are still in demand among races and organizations that can afford prebuilt ships but not their own research programs. A Raven ship, while not invulnerable by any means, can be a fearsome opponent, and many pirate, police, military and corporate organizations count these bird-men's ships among their fleets.
The Navy of the Unkindness itself, on the other hand, is not nearly as intimidating. It is common practice for ships passing through Raven space to take the brunt of their pompous pronouncements, put some weapons fire across the nose of the NUR fleet, and continue their journey chased by the grovelling of many black bird-men.
If actually attacked by intruders, the Ravens will pull back for reinforcing unless they outnumber their attacker at least 3:1. Their attack pattern resembles that of the flocking-attack action of Earth birds - many passes on a single target by hordes of ships. Coupled with the small nature of the bulk of their fleet's ships are the prevalence of fighters among even the smallest vessel. The goal of any Raven fleet is to overwhelm the enemy with fighters and starships, and they're very good about coordinating hyperspace jumps into and out of the battle.
Especially when the battle isn't going well. They're absolutely incredible about getting out of harm's way.
