You'll put aside your apprentices treachery for later, right now you need to decide if you should help the Beef Cake or not. You don't really want to lose your apprentice, but you also really don't want to get involved in a family dispute either. You think you're just not going get involved in any way whatsoever. No siree Bob. "Anyway as you were saying earlier about your sister. I don't think convincing her to leave is best thing for her safety wise."
The Beef Cake raises his eyebrow at you and says "You think it is safer to hang out her then go back home despite the fact that she will be marked as villain for being part of your gang?"
"Okay two things. One I am not villain, that is just PRT propaganda smearing my good name. Two I don't run a gang, this is a guild. I can only assume that is more PRT propaganda since they are huge lying booze hating heretics." you say, your eyebrow twitching. The PRT is going to pay for all of their many many lies, oh yes they are.
The Beef Cake continues to look unimpressed. "You can't really call it propaganda, the PRT is legally allowed to classify you a villain if you break the law. Also the Merchants are a gang, everybody knows this, you can't just declare yourself not a gang."
You frown and say "Okay I am not going to argue whether I am a bad guy or not, I know I am not one and that would just be silly. Look your sister has awakened and can use magic now. Using magic improperly is extremely dangerous and can end in tragedy. I bet my left ovary that the Bee Shaman, due to being a ignorant hoe bag, didn't realize that she was essentially selling her mind and soul to an evil bee. Now her parents are dead and everybody hates her. You don't want your sister to sell her body to evil bees do you?"
"I can't say that I do." responds the Beef Cake "But how likely is it that is going to happen?"
"Um, not very, but that does not mean there at not other legitimate threats that will be after her." you say. "Since she has awakened she will stand out in astral space and any astral predators will notice her. She didn't know how to set up any defenses until I showed her how and even now they aren't hard to pierce. I just taught her a healing spell and now if she gets hurt she can undo the damage. Doesn't that make her safer then she was?"
He pauses and says "You can/actually (pick one) taught her how to heal?" He sounds confused for some reason. Does he think you're shitty teacher or something?
"Yep. She is real go getter too. So she should have it mastered in the next day or two. I was thinking of showing her the basics of summoning next. Spirits are very useful allies to have and she needs to know how to get rid of hostile spirits as well." you say. "Spirits like the bees."
The Beef Cake looks unsure now, you think you are getting to him a little, you just need to give that final push. "You know how I was saying I could track people down once I saw their aura? Well other spirits and mages can do it as well and your sister has no way of hiding herself if she makes herself their enemy. You know your sister better than I do, do you think she would provoke somebody like that if she thought it was funny?"
Judging from his expression you nailed it. "She would totally do that." he says in a resigned voice.
You push to offensive while you have the advantage "If she stays they can't get to her and since this base is flying and invisible neither can the PRT. I bet the Transporter could whip up a force field as well." Time for the coup de grace "Tell you what I can go over anything I plan on teaching her first with you that way you know that is safe. If you don't like it you can veto it and I can plan to do something else."
He nods and says "I would like that a lot actually."
"Great!" you say cheerfully. Boy are you glad you didn't get involved and try to convince the Beef Cake to let his sister stay.
