Hi, I'm seeking recommendations for material to fill a gap in my Pathfinder campaign. The party will soon be 11th level, and I don't have any firm plans until 15th level, when I plan to adapt the final chapter of the Kingmaker AP into a climactic storyline.
I've already done a lot of work adapting Pathfinder Modules, AP chapters, and Scenarios to suit the campaign. Now, I'm looking for adventures involving either intrigue and infiltration, or cosmic, planes-hopping conflict (or both).
But basically, I'm curious to hear everyone's favourite adventures for this (sometimes somewhat awkward) range of CRs. Thanks!
