Lily became an apprentice mage in Arin's tower in which the mage is omnipresent, and omniscient. But not omnibenevolent.
Lily quickly learned the cultivation of the mind and mana but Arin who found her rather endearing also gave her a body strengthening technique for mages.
Lily understood it, but to temper your body with mana is far different then with Qi for the body is accepting of Qi which passively and slowly(or rather at a good rate for your body-that what fighter talent is) but mana must be forced into the body and pounded in and onto your cells it like forcing water into a closed full bowl vs pouring water into a hole -of various sizes -until the body grows.
Lily routine every day except Saturday was magic lessons, body-tempering, medicinal bath (to soothe her body and make sure the body tempering doesn't harm her/solidify the mana's effect in her body), 'private lessons'(brainwashing into loving-as a mother- and relying on Arin+ lessons, and cultivation. Repeat, 'Private Lessons still happened on Saturday and sometimes even cultivation.
At first Lily thought, 'even if she keeps me here I'll never love her just pretend to, for I am at heart a prisoner.'
But within a week the brainwashing(which wasn't spells and so couldn't be removed by a higher level) took effect and so Lily was thinking and saying,"I LOVE Mother Arin, Mother Arin and my siblings are my only allys in this cruel world, only mother can keep me safe, Mother Arin is the best! I also love my siblings Mother Arin." And soon she even dropped Arin and just called Arin Mother.
Lily even loved her life and 'family' she'd do anything for them and her previous family seemed dull, boring, failures in comparison... She DESPISED them.
