So I got a weekly group for a campaign but players have been mentioning putting current one to pause so I have been preparing a new one but its start has time related plot which i am not sure to keep surprise or tell them before hand.
Starting plot as follows, as follows:
1.Its a go back in time and save the world before its end kind of plot
2.upon defeating the void elder dragon when party of lvl 20 find its summoner who used a hourglass which turned back time so he could fight at his peak. defeating him a npc mentioned by surfacing himself and using the void dragon heart he can send them back 2 years so they could stop all of this from happening.
3.Party goes back in time to lvl 5 and with the hourglass which has 60 minutes worth left as using it one member of party can turn back to his lvl 20 self. They must stop the atrocity from happening by using this hourglass and things they already know form future to stop their past from existing.
Now I am not sure weather to explain all of this to players from start or have them run a one shot for lvl 20 stuff then ask if they want to play such campaign as keeping it surprise sounded nice at start but knowing how player preps char in campaign vs one shot could be a bummer.
