Nothing, she's good the way she is.

No. She has always been there for you when no one else would, you couldn't bring yourself to hurt her like that. Plus you both have a shared love of sexualizing women, if anything she's more of a horn dog than you'll ever be, It'd be a sin to deny her a chance at arcane degeneracy.

Just to be safe though you look for any protective spells; You love Gwen to **** but you don't trust her as far as you can throw her.

after you find a protection spell that only requires you to break your pinky and cut off a number of your toes which miraculously regrew after. you feel ready to take Gwen on as an apprentice.

You rang her and briefly wondered what you were going to possibly say to her but decided that you'd just wing it.

A groggy Gwen answered the phone with a “Vik? Sorry, but I have to get to work, I'll call you once I'm off.”

“Call in sick.”

“Vik I can't just-”

“-please? This is more important than whatever you have waiting for you at Arby's. Gwen... trust me, if you come over now you'll never have to step foot in that meat house ever again.”

“I... Oh all right. But this better be fucking worth it.” She said mock threateningly before hanging up... or just threateningly you could never tell with her.

You were splinting your broken pinky when you heard a knock at the door.

Your chair started to jiggle in excitement as it looked at the door. “More butts! More butts for sitting!”

“Shut the fuck up!” You shouted as you opened the door.

Gwen stood on the other side wearing a flannel shirt and jean shorts that accentuated her curves nicely as well as a black sunhat that contrasted her short dirty blonde hair beautifully.

“Who are you shouting...” Her voice caught in her throat as she looked at your hideously lavish apartment. “... At... What... What the fuck happened?”

“This did!” You said as you held up the Summa Crudelitatis. “Since your so into witch shit I thought that you'd want a taste of the real thing.”

She took a few steps in and almost fell over when she saw your new chair.

“Sit me! Sit me!” It shouted at it seemed to shimmy at her.

“AAAAAHHHHHHHHHH” Gwen screamed as she backed into your chest. “What... What the fuck is that thing!”

“Oh, that's what's left of my roommate. I like it much better this way. But that's not why I called you here, this is!”

You grabbed a knife from the kitchen and carved a series of concentric shapes onto your new chair, Then began to chant a long spell.

“Hurts! Hurts! Daddy stop!” It protested as the runes glowed on its cushions. After a while, it just screamed as a willowy mist began seeping from it and into you.

once the ritual was completed the chair was not but dust on the ground and you felt... fucking amazing!

“What happened? Vik What did you do?” Gwen asked as she stared at the dust on the floor.

“Oh, I ate it's soul. But don't worry you can only eat the souls of the cursed and the forsaken, and even if I could eat your soul I wouldn't for the same raisn I'm telling you about the Summa Crudelitatis. Because I don't want to do this without you, I mean you're my besty for life. Right?”

Gwen looked at you for a very long time. You could see in her green eyes that she was conflicted. You held the Summa Crudelitatis close just in case she was going to be closed-minded. You hoped it wouldn't come to that.
