High Charity ruins?

So something I noticed at the very end of the Halo Wars 2 trailer were some abnormally large debris. No, these aren’t massive tons of destroyed vehicles crunched together, but rather, they looked VERY similar to the debris of High Charity that we saw when Chief entered/left High Charity after it crashed into the Ark.
Maybe the Banished could be possible survivor of High Charity or a group of covenant from the Battle of High Charity who came back to the Ark to gather what they can from High Charity’s ruins.

Interesting stuff!

I thought they’d had some kind of association with the enemies in Halo 4 and 5 that were covenant, but now refuse to join with arbiter and the elites after the truce. I assumed the ‘banished’ was now those enemies official name.

Not sure to be honest because I can’t really find any information about the Banished, but I could see that being the story as well.
