Now with The Witness gone, what do you think his forces will do

The Final shape has finished and the witness is dead. with that I was wondering about post Final Shape and what The Witness's forces will do now that it is gone. we currently have ideas of where each faction is currently situated and a basic idea of the immediate future from Crow's report. Eramis is up and disappeared with her fallen forces having no specific leader. The Sol Divisive has essentially lost their god and meaning while the other vex forces might be turning Failsafe into a vex god. The Taken are even more lost without guidance so who knows what will happen there. Shadow Legion are unknown about their future since they were being mass produced and lead by the witness. Caiatal clearly wants to wipe them out as the last vestiges of Calus. Xivu Arath is mortal and has something planned, but she is heavily vulnerable. The Witness forces that were introduced in the Final Shape clearly have a command structure and are zealots for The Witness so besides whatever is going on with the Vex I feel like they will be the closest threat next to both factions of Hive.

An out of left field threat I see will probably be the old tower factions that left the city. maybe the Future War Cult and Dead Orbit since they kind of lost their main reasons as factions with New Monarchy coming along for the ride.

So I'd love to hear what people think will happen with these factions since there is a massive power vacuum caused by The Witness's death.
