Just an FYI: Troll Lord Games is coming out with an epic adventure path campaign called "The Cult of Yex". It should be out in a few months. It is a hardcover full campaign that contains:
- a regiona drop-in setting (desert) suitable for insertion in any campaign world. The setting includes two fully detailed drop-in city settings.
- 8 full sized modules designed to be played in an epic series taking PCs from 1st to 20th level. Each module stands completely on it's own, and can be used as a stand-alone module.
- Dozens of new monsters, magic items, spells, villians, NPCs, etc...
Most modules have an extra-planar component. Two feature a demi-plane, two take place mostly on the astral plane. The final module in the campaign takes place almost entirely in the Abyss, with the party having to choose the lesser of two evils in demon war. There are plenty of dragons in there, as well as political intrigue, puzzles, and about 40-50% dungeon crawl.
If this is all sounding like a shameless plug.... well. It is! I am one of the co-authors, and I hope you'll check it out. We have been plotting, writing, editing, storyboarding and playtesting for 4 years now. I promise, we have gone slow, and done it right. And with 8 modules and three detailed drop in settings, it is a better value than even dungeon mag. I am at your service if anyone has questions.
