if it's a bad religion, then how about removing it if it don't have any good benefits. Replace it with something else, or change it so that we can make a temple out of it and have a chance that one of our people can become a drake-man, or something else. I don't like religion that don't do anything good.
Keal, that's a great Idea, instead of staying at Age of Rebirth, make a set year that will occur into another age, like for example, Age of Rebirth is the first Age and it will end at the year 200, 201 is the new age, The Age of Fire, some of the terrains, even the island will be transformed into volcanoes and become pits of lava that can degrade or destory your things. After the year 400, another age will appear, the Age of leaves, a environmental age that all tarrains transform into forest and jungles, very useful for the people who have the Fellowship of Leaves. After the Year 600, the Age of Ice will began, a Age that tarrains become tundra and snow, and the seas covered with Ice, like an Ice Age. After the Year 800, the Age of apocalypse, where things will go chaos then after the final turn, the world explodes and the Ages restarts itself to become another Age of Rebirth after the planet is reconstructed.
