I'm guessing too much Light or Darkness would still cause The Roaring in this case?
The roaring might still be a deltarune thing in this swap universe. In this case however, it's moreso that chaos is triggered by not actually bringing something out, but it depends on their action. For example, the grave event which leads to dark and light mages exiling monsterkind. Light, dark, monsters, each plays a specific part in harmony-keeping according to the WARPEDSUN symbiology. Who knows how the outcome would play out now that the balance has been shifted immeasurably. A huge war can happen anytime and that's where they'll all face the suffering for all eternity.
