I'm praying Jan to continue releases of "NG+ mechanics", release one of the Charizardite or delivering well the Paradoxs Pokèmon, since it's a form concept I really enjoyed. They are handling well the Hisuian Forms, so...
Edit: now that I think about it, previous versions had Light Profecy and Crystal Ball telling the origins of "four light not born from men", obliviously some details changed, but the original concept is explained: Melia, the one with Arceus's light; Aelita, the one who desires to lead other; Crescent, the one who lost a loved one (she's Interceptor and her origin story...kinda makes sense?) and MC, obliviously. But I want to remember who instead the Dark Profecy talked about...
