If Tau is your flavor, around about the time of this. The Empire launched it's 4th major expansion campaign, when
gw spoke of this they ended with some.artwork of chaos possessed butchering firewarriors, so we can guess what they met. They're also fighting with the Imperium again over the Damocules Gulf sparked by the recent warp incursions.
Fourth Sphere Expansion got swallowed by the Warp storms. It wasn't said if they were destroyed or just sucked into the Warp which means they could pop up anywhere in the galaxy (potentially making them relevant to the next major campaign).
The Fifth Sphere Expansion is underway. The Imperium might be weakened but the Tau Empire is now bounded by Necrons and the Great Rift as well as having Imperials to their West so they may struggle too.
Leviathan's assault on Baal was thwarted by Chaos. When the Great Rift occurred a warp storm swallowed the Hive Ships attacking Baal and Ka'banda destroyed Tyranids on at least one planetary body. Guilliman then rocks up and helps scour the remaining Tyranids froom Baal itself. Again it's unknown if the Hive Ships were destroyed or simply sucked into the Warp so they could go anywhere.
Chaos Primarchs are getting up to more stuff. Chaos is infighting again after their brief united push. Cawl is super tech savvy, may be using an actually AI, Gulliman doesn't trust him. Personally I'm hoping for some Imperial infighting but other than Guilliman clashing with Inquisitors over trying to create an accurate summary of the history of the Imperium it doesn't seem to have happened yet.
Oh yeah, Guilliman basically has the authority of the Emperor up to and including bossing around the Adeptus Custodes. So yaaaaayyyyy for reversing everything he did before he went to sleep. Well I suppose he hasn't reunified the Imperial Navy and Guard. Only Space Marines are trustworthy i guess.
