Flavor

The one character that started an entire world just by existing (not in-universe)

Lives in an epic hacker cave under a skyscraper in the center of the capital, where she bought out almost the entire basement; there's a lot of screens and keyboards for different purposes
Her magic is basically willing artificial intelligence into existence.
Can hack anything and doesn't use this power for good
Basically an information broker mostly. Hoards info about anything she can find
The great elf ruler knows about her and her doings; they're besties and she gives Flavor enough political protection to do whatever
In cahoots with the mafia
Also in cahoots with the black market and the Black Doctor (also besties)
Buys custom-designed lollipops that look like cigarettes
Terse talker
Irish accent (local equivalent)
Has a brother a couple hundred years younger than her, he's a musician. She sends him gifts ranging from boxes of sweets to stupidly expensive violins.
