Hope this makes sense. I am continuing a campaign someone else did a couple sessions of, Dragons of Stormwreck Isle, dnd 5.5e if that matters. The concept in my interpretation is several adventurers go there because they're seeking something at the island, wisdom, spells, etc. One PC is looking to find out what has happened to his long lost grandfather. This whole thread has nothing to do with the prewritten material other than there's a dragon type quest to resolve and the rumor about the grandfather is he was carried away by a dragon over 50 years ago.
I have planted a couple clues that would lead the crew to think this PC(paladin aasimar) has a "twin" that has been seen on the island and that there are some signs of a time travel vortex or field or something. I'm thinking maybe they'll find the twin and realize it's actually the grandfather and there's a time warp. Then I'm thinking maybe they'll get pulled into some other world/timeframe/something and that might be the new proactive campaign. I'm planning to tell the actual players about these concepts a little bit each week as we resolve the pre-written scenarios/adventures prior to the time warp.
Any thoughts on how to transition in a cool or conflict driven way? Or any suggestions on moving forward?
While on the island I have a sorcerer & wizard who both want more magical powers/spells etc., a tabaxi rogue who wants cat nip but is holding back on other motivations, a warlock on a quest for knowledge, patron still a mystery.
Open to any reactions, thanks.
