Is soraka a member of the people that imprisoned aurelion sol?
Also it says she watches over an isolated tribe of vastaya teaching them her healing ways, could the new (likely feline vastayan) support champion perhaps be from this tribe?
I do not think 
helped the Targonians trick 
into servitude. However, whether she'd considered herself one of them or their ally is up in the air. Based on her lore, I don't think she would necessarily have stopped them or resent them for it.
I have a theory that the Targonians overthrew the Celestials, much like how the Greek gods overthrew the Titans.
I believe the Vastayan tribe they are referring to are the Marai, 
's tribe, however we'll have to wait and see, it could be a new tribe indeed.
