I've been running an expanded AoW campaign based in Eberron since...well, let me put it this way. I didn't know my wife when I started playing it, and now I have three kids. :D
I've mixed and matched everything. When the warmage was plane shifted by the beholder in Spire of Long Shadows, she ran a solo game for a bit using The Impossible Eye as a base. That tied in nicely to fighting the ifrit in The Library of Last Resort, whom I reskinned into the exiled noble from the City of Brass.
I added in a lot of Council of Thieves into Redhand, and Zeech's party was for the survivors of The Sixfold Trial. Now one of the party is the Prince of Redhand and slowly being corrupted by Lashonna while the rest of the party is trying to put together the Rod of Law to prevent their new little princedom from being destroyed by green worms.
It is crazy to think of how much I have mined from Paizo's adventures over the last decade. Thanks, guys!
