Very important. As Evangelion has a very airtight story that doesn't allow for a very good RP, I've been forced to make a full AU.
-Angels are more common.
-There are many Children.
-The canon Children literally don't exist (unless you want to do an individual RP).
-EVAs are also much more common, and come from all over the world.
-The Third Impact isn't possible.
-The canon EVAs also don't exist.
-You can absolutely be the First, Second, Third, Fourth, or Fifth, or whatever child. As the canon characters don't exist.
-The Children do not have to be fourteen. As long as they can be considered children, it's alright.
