I don't mind Askellon right now, and Enemies Within did a lot to build on what was there. In fact, I'm setting a whole campaign in Port Aquila based on what was provided in the core rulebook and Enemies Within.
I think that people forget that Calixis' lore was built by numerous supplements and source books. At first, it was also just as simple.
The difference in this case is that we're a year in with only really two books to suport the line. A little frustrating.
Still, I have faith.
