Ive thought about this for awhile.
How would the UNSC and if any disbanded covenant races be inside the forerunner planet?
Would UNSC and Sangheli forces(if theyre allies in H4) be fighting a conflict on the shield world against this ancient enemy?
Could they have used some type of teleportation system retrieved from a forerunner shield world/Halo ring to be beamed to the planet?(wild guess)
Will they arrive later on,perhaps if Chief sent a beacon later on?
Will these factions not appear in H4?(hope not:(…)
