D&D roadmap:
Obviously we need to finish the Gundren Rickseeker Arc, then face off with the Dragon as a final boss, that will conclude the first campaign. At this point it's a small campaign, sort of like a one-shot. The expected level is 5-6, you will be both a hero and a dragonslayer if all goes well. I believe you will all be level 5 when you face the dragon, which is inevitable I suppose.
Other possible outcomes: Alice has access to her ship, Yulya and Cat both should get a chance to get what they want, can both of you please let me know what a mid-game achievement might be for you? I'd like to see what kind of closure we can have for the finale and take a break after that for a while. There will be some loose ends, teasers that you would know by now. I consider this first campaign like season one of an Anime, either we decide to make a season 2 or start a new series etc.
Future campaigns will have to be considered carefully. So I'm just thinking ahead. I'd need time to outline and plan another arc once we get through this one.
