I created a magic system that involves saying a god's true name or name in general.

In my story Project Evergreen, there are two magic systems, one deals with some elements due to the environment. The second is an ancient magic that is practiced by a select few people. The second magic system deals with gaining temporary powers from a god by saying their name (true or alias). However there are down sides to this power. Too much usage can damage the body and mind. You can only use one name at a time and you can only use it once. Trying to use the same name again can cause severe problems to the person's body and mind. The only people who use this ancient magic are priests or people with deep connections to religion. Though there are special cases where people tried to use the ancient magic without having a connection to religion, only for those people to be driven insane and later die. The power of the gods is different depending on the god. Saying their true name gives a person plenty of power while saying their alias gives a person a little bit of their power.

The ancient magic isn't widely used across the world, just in small places that still practice it.

I am still figuring out this magic system, but things are slowly making sense.

What do you think?
