Text Color: A nice shade of violet
Biography: Years ago, the kingdoms of Nescin and Giam had been locked in a seemingly endless war. Neither side could gain any more territory without inviting swift and decisive retaliation.
Many thought the war would only end with one nation gaining an advantage and overrunning the other. Yet despite all predictions, the conflict ended peacefully, and few knew the full story of why.
But throughout the kingdoms, there were tales of a young girl who had been instrumental in ending the war. In some versions, she was a princess of Giam; in others, she was a traveler; still others said she was a rogue soldier of Nescin. Whatever her identity, the tales agreed on one thing: she had a mystical vial that could create potions from nothing, and refilled itself whenever it was emptied.
Mychela was an apprentice witch who found herself fascinated by the story. She wanted to know more about the vial and how it worked.
For a few months, she searched throughout Giam and even parts of Nescin in hopes of finding it, even just shattered fragments. She found no sign of the vial itself, but she did start to piece together more of the story.
As she did, she realized two things - first, that the girl had created the vial herself, and second, that doing so must have taken immense magical energy. Inspired, Mychela decided to make her own vial.
With a bit more research, she was able to find the rare crystal the vial had been crafted from, and also located a powerful source of mana to draw from. She shaped the vial, headed to the right spot, and prepared an incantation.
As soon as she finished, the vial filled with a strangely-colored potion. Mychela was eager to experiment and find out what it could do.
But before she had the chance, she and the new vial disappeared.

Description: Mychela is a young witch in her early 20s, and she dresses the part. She's very curious, and when she takes an interest in something, she goes to great lengths to learn more about it. The vial isn't the first item to catch her interest in this way.
Now that she's made it, her primary interest is in learning how it works. What sort of potions does it produce, and is there a way to predict what it will create?
Being dragged into a battle to the death is really only a secondary concern to her. She'll get along fine with anyone else as long as they don't try to interrupt her research. In fact, she'd be delighted if they'd volunteer to help out.

Weapons and Abilities: As a witch-in-training, Mychela knows a fair number of basic spells, mostly for utility. She knows a basic fireball spell just in case she needs to defend herself, but even then she prefers to use it to scare attackers off rather than harm them.
And of course, she has the newly created vial, which produces a variety of potions and refills whenever the potion is used up. Though she hasn't had time to test it yet, if it works like the one in the story, attempting to use a single drop of potion will just result in the whole vial emptying and refilling. She has no idea what sort of potions it will fill up with, though.
But she's very eager to find out.
