Cosmog is not part of the main story and only shows up during the postgame. Lusamine's plans instead involve Necrozma.
Lillie becomes a trainer with an Alolan Vulpix, similar to her anime counterpart.
Lillie still departs on a journey at the end of the game, but where she goes is not disclosed(it's the Gen 8 region).
