Very important must read

I want to ask if you would all rather that this story only happens in the Halo universe or would you like me to include other universes like marvel and Star wars do note that if I do include them they must include space segments in the original work this is because those world have no detail on what to expect in space however the main universe will stay as halo meaning they will alway come back to it but I leave this decision up to you guys since I can not seem to decide since both have merits and disadvantages and if you guys decide that you want it than i will do of a way to fit it in.
