A farm girl, hailing from Brookheim, a small backwater town in the Hesse region of the Republic. Despite her notions, she's ultimately still a provincial. There's a joke in the Republic that every Hesse girl gets fed well, and they have more than their fair share of minotaur in the blood. There's more than enough truth- Hesse is the breadbasket, and they're well known for their feats and "bountiful" women. But Alexandra missed out on that "bountiful" part. Tall, skinny, and infamously flat-chested, Alexandra is well-known around town for quite a few things.
The first? She's quarter-elven, but the elf blood came out strong in her. It means she's tall, long-haired, long-legged, and slender. Not fragile, but she frequently comes down sick. She has the dubious distinction of towering over just about every man in her town. It gives her a lot of grief. Especially because she's also flat as a washboard.
The second? Her talent for magic. A great number of humans in the Republic have some amount of elf blood. It makes magical talent a common, and unfortunately unremarkable thing. Alexandra lives and breathes magic. She has quite the raw talent for spellcasting, what she lacks is formal education. It's given her somewhat of an inflated ego. She has a fiery, haughty personality born mostly out of her being the best magician in her town.
The third? Well, she's the first Hero selected in a century. In a time of unprecedented peace, prosperity, and tranquility. It's no small thing. The last batch were there in times of war, disaster and chaos. It's a source of a lot of stress for Alex, who up until then was mostly intent on finding her way into a cushy life, reading books, and studying magic.
