Protectors of the multiverse. Roleplay m/interactive book

So, I got this idea for a book, but I can't figure everything out yet and can't decide what characters I wanted so I decided to make it a role play instead. I might eventually turn this into an actual book one day, but for now I think t would be best if it was just a role play instead.
Also, this is going to play with the idea of multiple earths existing so, I guess this can count as a Science Fiction role play/ interactive book mixed with some fantasy. I guess I'll probably put it under the category of random until someone helps me find a better category for it.

This is a role play/ interactive book (whatever you want to call it) about an organization made at the dawn of time that was created to keep all earths in the multiverse and the timeline for them all in order. All people working here all have bloodline that has been working here since the dawn of time. Once you turn four years old they begin training you to take classes to be able to contribute to the organization and society. This follows the life of two students here trying to live normal lives outside of here while trying to deal with the looming threats from an enemy organization built long ago who also, are trying to keep all those they love and the people of this multiverse safe from a total multiverse war, that could result into total extinction of all the multiverse and themselves with only the worst of the worst left alive to restart the worlds population.
