Soooooo . . .
I have been GMing a Bi-monthly S&S campaing for about 2 years. We had a short excursion into Serpent's Skull when they jumped the sandbox. But of the group of 4 that has survived to level 9. One recently moved and another will be moving and only has one session left they can attend.
We considered recruiting more players but they are going to be 10th level next session and I am putting my self in the shoes of a new player. They need to make themselves familiar with the events of the game so far and make a connection to the story which really hinges on revenge against Harrigan. Of course there is also the possibility that we don't come up with those who wish to join.
My thinking was to set up an ending to the campaign. To do this I was going to tell the party to level up to level 16 (about what they would be at the end of the campaign). Basically do a flash forward in time adventure to the point that the captain is the new Hurricane King, Bonefist is dead and Harrigan as well. It would be about a year after they consolidated their rule and news that Harrigan has returned from the grave for a grudge match.
Here is Harrigan's new ship the Wormwood's Revenge
Harrigan Returned from the Grave
It would basically be a bit of role play and build up to the ultimate of Big Bad Guy battles.
What I would need to help flesh out the idea is if anyone has a list of treasure that they encounter from the course of the AP to help outfit their characters.
Any tips would be helpful.
My thinking was adding a the Devil-bound template to Harrigan as well as some fun returned from the dead crab dude abilities.
I don't have the list you seek, but I can point you to Legendary Games' Treasury of the Fleet, which is basically a pdf full of S&S-themed magic items.
Thanks @tbug
