How to start an organized special rp group?

[Zygoeths]

if you've read my storys about zygoeths, u probally know hes sorta interesting. Well.... id like his roleplaying to become a roleplaying in discovery(such as tenebras and others). I also just wanna know if i have to have a certain amount of cash or what ever. It should fit into the rp fine, it doesn't really disrupt anything rp related except for my character is searching for a Master Brain. My group will have order ids and order tags, but have roleplay selected names. I don't know if i need permission to do this (since its sorta like a clan) or if i can just do it. But i think it would be good to have a crazy guy running around looking for a Master Brain XD. And then if i can get my character powerful enough i can make ppl fear the group also XD. I just think it would be fun, help me out here.
