"Because x did this that means it's okay to do Y". Poor argument, only made worse by you being butt hurt about what someone on a premium Minecraft servers who you don't even know says to you. I have gripes with the lore piece, not the name, story or whatever (everyone takes influences from something), but some of the abilities. Even if they're t5, some things you have stated are/seem relatively broken or can be easily abused (more on that another time).
I do have a question though. How do you plan on implementing kin? Or I suppose magic implementation in general
Edit: I don't know if you're trying to be Lovecraftian with some of your wording or naming conventions for thingies but I'd reconsider a new flavor. Eldritch tickles my peepee too much
