I'll repost this here, since the other thread wasn't about backstories, but that is what interests me more than simply class and race. This is the character I'm currently envisioning for my first playthrough. I'm not quite decided about whether it'll be draconic bloodline(bronze) or storm sorcery. Both are lightning-themed and the backstory works for either. It'll depend on how storm sorcery is implemented in the game.
So here is...
Vaenye Andrallat
Not-so-proud member of a minor house in an unspecified drow city, and one of the probably not too rare drow who hate Lolth and her priestesses, but never dare say so because that can adversely affect your health. Too careful to be a rebel, too free-thinking to conform, she kept alive by keeping a low profile and spending,intermittently, half of her life in the cracks of drow society [urchin background]. She also had a knack for magic but that never amounted to much beyond theory because of the fixed gender roles in her society. Anyone can be a fighter, but as a rule only men are wizards and sorcerers while high-status women (among which she was not) become priestesses.
Then there is the dragon. As a drow you learn to be self-reliant. After all in the absence of external enemies, the most deadly danger for any drow is another drow, and you never feel safe unless you’re alone. So she made expeditions into the cave systems surrounding the city on her own, and on one such expedition she found an egg. It had a crack. A little dragon with brown-red metallic scales hatched while she watched. She liked it instantly, but of course she couldn’t keep it. It would only end up on a bloody altar. It couldn’t be far to the cave where the mother lived, and she found it. There was a scary encounter with an incensed mother dragon who understandably did not trust her one bit at the start, but eventually came to understand that Vaenye had saved her child. The dragon gave her a gift she conveyed with a touch. An invisible one, she said, and that it might be some time before she could make use of it [Draconic bloodline sorcery or storm sorcery. IMO the dragon could gift either]. It also changed the color of her eyes to an odd shade of violet-tinged grey [not sure if the CC has that...hmm].
Some time later her stealth skill failed her and on another expedition, she was caught by a patrol of illithid thralls, to become yet another subject of the experiment the illithids were running on the surface. But coming to the surface, her magic began to stir. As the nautiloid that held her captive crashed, she fell to the floor, and there was a strange noise outside. A loud crack, followed by a gentle roll. She did not know what it was, but it called to her. Something like blue fire materialized in her open hand. And she was forever lost to her old home.
