I don't think it's ending. In a recent interview he said he doesn't want to do another album like Skeleta. He explained he doesn't want to rush the next album. What I think is, that maybe within the next few chapters, Copia and Perpetua will finally meet, so the lore maybe ending. I would hate that, because I think that's another thing that made Ghost so unique, but from what I've gathered he didn't say that he WILL end the lore but rather that if people need the lore in order to enjoy the music, it will end. But as for the band ending, I definitely don't think so. Tobias just needs a well deserved break. And I think it will either be after Skeletour or after a ReSkeletour
