This is a very good concept, which I found. Listen up:
Each race has its own Temple. Temples are giving you some military units, increasing your Morale value and gives you the best spells, even if you have low experience level. I decided to make this concept "Open Source", 'cause it has a lot of fun.
How is this a Concept? You place a building, call it a Temple, and run some triggers at it.
