first want to clarify, not asking you to do research for me, just advice on a direction to go :) i want to send my best friend some sort of guardian to protect her and give her comfort and affection when i can't, so i'm trying to figure out what things to look into to do that. i have no intention of rushing this! it's definitely a goal i'll need to work up to over a long period of time. i just want your advice on where i should be looking to figure out what kinds of things i need to learn first
Look into thoughtforms / servitors, honestly. I have tags for both on my blog. It is a branch of chaos magic, where you create, essentially, an energy being delegated to perform a certain task (or multiple tasks).
