If we're switching to Republic this turn and we decide that we don't want to use specialists in the Uber Isle towns we'll have to buy temples in some of the towns there. Here's a list:
AGC - 20g.
BFM - 40g.
Boom Town - 84g.
Site E - 96g (can be delayed by up to 4 turns).
Thebes - 108g (can be delayed by up to 7 turns).
