At least with the events of Transformers vs Visionaries, there is an actual habitable place to stay on Cybertron for the Elonian refugees now there:
To clarify for those who have not read the series: after the planet of Prysmos was destroyed, a series of events lead to a number of the survivors establishing a city on Cybertron. “New Prysmos”.
Rendered just about barely habitable by a mystic artiact of the mystic population known as the “Talisman”.
But there was conflict between the residents of New Prysmos.
Some, namely most of the Spectral Knights, wanted to try make peace and establish relations with the locals, along with simply improve the conditions of the city they had.
But others, such as the Darkling Lords and the majority of the civillian population, were not happy with the arrangement.
They wanted the entire planet terraformed into a new world for them, not viewing Cybertronians as people and as such not caring that the process would kill them all.
Things escalated because of that.
Eventually however, the combined efforts of some Cybertronians and Spectral Knights detonating a counter bomb of sorts to prevent the terraforming, along with Galadria and her attempts to use magic to save Ironhide’s life- all of that reacting with the Talisman:
Well, in the words of her and leader Leoric, this happened:
It will be very cramped.
It already was, even with just the Prysmosians residing in it, but we know the Knights will be willing to help the best they can, along with Cybertronian efforts to assist and it will be something habitable for the Elonians at least.
