I thought on this a little: the Elves could be manipulative bastards. Just consider it: you have limited resources, limited space, and all those humans and orcs breed like rabbits. The only thing that keeps them from fillingg every space is that they kill each other constantly.
What if they stopped?
With a little encouragement, they are prone to go bashing each other again. With elven guile and sorcery, this is all but child's play.
So, the elves play the factions off againt each other, to draw attention away from their secluded homeland.
They may even acknowledge that some humans have potential, and lure them away, giving rise to all the myths about faeries abducting children.
Echo likes, a lot. Especially the aspect of how they are not hollow armor, but rather armor that wears people... or pieces of them, at least. I can really imagine a bunch of Knights holding down a captured victim, and forcibly dressing him up in the armor, then letting him rise as a complete knight.
Located in a backwater region of space, the station (CRN-13) once oversaw the terraforming and development of the world below for the Celian Republic.
Plunged into war, the interstellar state shattered and left the station unattended; in a bloody coup d'etat, the commander of the stationed navy forces took control. Now, fifteen generations later, the descendants of the rebels still rule the world from the station above.
Holding the colonists captive with threats of death from above and enticing the planet's mighty with promises of modern medicine and technology, the spacers live in opulence and plenty, attended by slaves and lacking nothing. Below, the landlubbers have to do with anything from medieval tech to industrial age machinery.
Disconnected from galactic society, Corona station faces troubles of its own - some systems that cannot be replaced locally have begun to fail, and the populace is growing more decadent and useless every generation.
A secret meeting place for rebels, dissenters and members of persecuted groups, this is quite a busy and exotic place: you can meet the last member of the Sankha, who were hunted to extinction, various weird pairings of species, rogue psions and underground artists, escaped political prisoners and members of strange religions.
Where is this place, you ask? Why, right in the belly of Apollo Prime station, above Earth, third planet of Sol, the busiest place in space. Hidden fortunately by a bureaucratic error and a faulty calculation from feet to meters, none would suspect the Candle's existence.
Its secrecy is maintained by Abu, the founder - an exceedingly cunning telepath. He will scan all newcomers, and subtly implant a suggestion in them: if they betray the sanctuary, they will forget any and all details about it.
It's a decent sub, though talking skulls and annoying ones to boot are no novelty, especially since Morte (Planescape: Torment)
Hence, I recommend checking out Morte.
Also, as a doctor, I don't really think the name is too good. It could use one that's easier to yell, especially in combination with "shut up!", and a funny one at that.
I like their creation story a lot - they're a by-product, accidental and misguided, yet to find a place in the world.
Where I could see improvement is the following:
> Their appearance is archetypally demonic, yet uniform. I'd expect more variety and perchance a slightly more innovative take wouldn't be bad.
> I'd like to know more about their culture.
> Just curious - why the mistyped Valkyries, Shadows, Dragons (Adraghan = a dragon, yes?), Titans, Fey, Trees, etc.?
