It's not my favorite method to create character'sbackgrounds; I have an agreement with my players that they can create their background freely, but if something is missing, I'm free to exploit the blank areas of their character's life. But, my players are more experienced. Your submission is a wonderful idea for those who are not used with the character's background creation process. If a new player comes by, I'll use it, to make things easier. Congrats!
Another nice piece. Fear seems play an important role in this setting. Or maybe I'm reading into it more intended. Horse-Lizards are awesome! Picturing elongated, reptilian horses, ribs exposed, gaunt, probably a sickly grey with a long tail. Nice!
Also: Death Seekers are scary.
Ah, somebody here likes Five Finger Death Punch, eh?
I really like this race. In fact, I might use it in a campaign I'm thinking of. There's an area in it called the Volskari Dominion, which is essentially like Magic North Korea... With larger guns. The people there are fanatically loyal to the ruling regime, and have repeatedly marched to war for the dumbest reasons and for the smallest slights imaginable, like if someone declared war on the U.S. because they held the Olympics in Seattle. Anywho, I was originally going to have the Volskari people be humans with weak immune systems (Volskaria is highly volcanic, and the air there is so high in temperature that very little bacterial life can survive- no doubt I'm butchering my biology, here, but I'll work on that later), but I have to say that the Shalari are a way better fit for that sort of horrifying, utterly insane regime that I'm looking for. Also, the idea of a group of Death Seekers fighting an elite unit of CDN Marine commandos is pretty awesome.
This is going to turn out to be an interesting setting. I really like the fear they won't call fear aspect of their relationship with Daemons. Very cool. Not much I'm longing for after reading this. They do seem reminiscent of Orcs, now that Dreamer mentions it. Not a bad thing, per se, but I can also see Echo's point about uniformity. You might have just described the archetype a little too well and it makes it easy to picture a horde of these guys with little difference other than height (and maybe wings).
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.?
