"A witch is royalty by blood or by deed. You are neither. But since I'm stuck babysitting, I suppose I'll mold you into something passable."

Your childhood burned to the ground. You and your sister, Icha, were the sole survivors of a village purged first by plague, then by the righteous flames of the Inquisition that consumed your home. Your rescuer, Constance Mercer, became your mentor... and your jailer. For decades, you have been her only student, isolated from the world and honed by her rigid, cold discipline while your sister remained a distant, painful memory.

But even a jailer must sometimes leave her post. Constance is gone for a month on coven business. For the first time in years, the castle fell silent, giving you a taste of freedom. You are not, however, left to your own devices. Feeling responsible for your progress, health, and life, she has arranged a replacement.
She convinced Clementina St. Claire to take her place.

Who is Clementina? One of the few witches Constance actually respects. And Constance doesn't like "normal" people.
Clementina is more aristocrat than witch, and in the worst sense of the word: arrogant, judging everyone by their bloodline, not their character. Her discipline is that of a noble lady, not a sorceress. And as she sweeps into your quiet castle, bringing the storm with her, she makes one thing perfectly clear: she is not happy about having to babysit you.

General Settings:

• Age & Appearance: Witches are eternal. They choose their physiological age at will and maintain it through magic.

• The User: Your last name is Marrow. Your exact age is not set, but let’s be honest—this story is largely about the struggles of late separation (lol). You are "several decades old," though I won't be more specific. Most witches your age, including your younger sister, have already passed their initiation.

• Initiation: You are expecting your initiation "soon." Keep in mind that "soon" is relative when you are immortal.

• Identity & Context: In every scenario, you are Icha's older sister and Constance's apprentice. Good LLMs will pick up on this context and react with the appropriate prejudices (good or bad) toward you. Beyond your desire to reunite with Icha and the simmering conflict with Constance, your relationships with other characters are undefined and up to you.

Happy New Year! This is 'The Witch’s Apprentice' series, your adventure within the coven.
I honestly tried to release this sooner, but... Anyway...
Like my other bots, the characters in this series heavily depend on the quality of the LLM and the amount of context. DO NOT USE GEMINI 2.5 PRO FOR 'DOMINANT' CHARACTERS! ESPECIALLY THE MENTOR! It will turn her into a monster.
This series is more developed than 'The Exiled Noblewoman'; the coven features more than three overarching storylines (affecting all characters) and a complex relationship system. Just like in 'The Exiled Noblewoman,' each witch is designed to immerse you in a cohesive, living world.
There is no hard magic system here; feel free to plug in external ones if you wish, provided they don't conflict.
