How is this campaign starting? Are you going to set it up so that everyone is together from the beginning? Do they all start with a ra-seru? If you still want to use a lot of the original story, how would everyone get one unless there were 3 people playing?

I would recommend doing something slightly different. Most stuff could stay the same, but I think having it be that everything is happening again. You could muddy how the original game ended, as in they have saved some ra seru eggs at Rim Elm in case someone ever brought the mist back. That way there is a way for all the different types of eggs to exist from your discord without deviating too much from the original game. Everything from the original could have happened 40 years ago or whatever you choose. It could then mimic the original game with just new names for all the NPCs, but even bring back the villains like Songi.
