Everything about this request is open! I would love for the Master to have a companion. Male, female, alien, human...It doesn't matter to me. I would like to give you as much creative freedom as possible so we can work out how they met together and why said companion decided to go traveling with the Master. I know all of this is very vague so please PM me if you have any questions!
I'll take the companion if you want. Making an alien that somehow ended up on Earth (powers/ 'human job' still have yet to come up with, but I have ideas)
