Skip School, Make Dragons

Artifact Forge doesn't make monsters. She's a bioengineer. She creates exotic magical livestock, upgrades cats into witches' familiars, and can turn you into a goblin if you accept the risks.
She's also thirteen, and has arrived in Goblita to learn her uncle is dead, she's inherited his business, and has a demonic cousin her age. Don't worry, Artifact can handle it. She's a prodigy! Give her a bioengineering challenge and she'll make you something better than you wanted.
…which is the problem as her messenger dragon turns into a ravening chimera, her new cousin gets her involved in a burglary, and the kids at school drag her into their dungeon crawling hobby.
With all that plus running a business and household like an adult, will Artifact have time to actually attend classes? Ask her again after she saves the city from the disasters she caused.
