I was looking over the new story feats and this one stood out a bit... The feat description is available here.
The examples as listed are a new temple for your god on the site where an old temple was destroyed, or an academy for students to unlock the secrets of the universe.
Now, conveniently pathfinder has added suggested buildings put together with their own Capital rules on page 107 in the Ultimate Campaign.
An already finished temple costs approximately 1400 gp, and that's paying double for all capital going into the structure.
A cathedral, described as "a center of religious and spiritual leadership", is priced at 4960 GP.
An academy is a little bit pricier, it comes to about 5360 gp.
Going further down the list, the most expensive building on the list, the Palace (described as: A grand edifice and grounds demonstrating wealth, power, and authority to the world), comes to 19 640 gp. And again, that's double the cost of building one.
So the temple or academy you need to build in order to qualify for the Goal on this feat is approximately the same size as five palaces stacked on top of each other.
I guess my question is as follows: Is it possible that the gold piece cap on this feat was set before the building price rules was fully ironed out?
