>>33753578I figure that a while ago, but what this made me realize, is that there's a scene where they show fused solgaleo captured on the top of that tower, which made me believe that they have control over necrozma and made it capture solgaleo/lunala and bring it back to their world, so they could power up the tower and have light OR they're having necrozma use his powers to turn Solgaleo/Lunala into the Sun/Moon they lost, so they have natural light again
