Hello! So sorry about the delay, it was my mother's birthday and I was a bit busy with her the past few days. Oh goodie, it sounds like three different worlds might be where we end up playing. I do like the idea of a pair becoming perhaps more antagonistic than heroic, then say, compared to the others. I had an idea about mirrors connecting the worlds. Say someone looks into a special mirror shard and sees them in their own world normally but from time to time could see themselves in one of the other worlds, with other people. It could be a way to transport to each one? I think the idea of a fantasy, a cyberpunk/sci-fi, and then our modern world, might work out? Of course we can decide if our roles are related or look similar or whatever, I think several options could take form here.
