Unfortunately this is a fairly recent campaign, but the Antithesis could definately have a part. You have the right idea. This is essentially a giant Cage Match between the followers of individual Chaos Gods. The Imperium is there to ensure that there is no winner in this struggle. So anybody that has a Warband or Champion devoted to a specific god can join in. They can also participate as part of the Imperial effort.
