Forum:Introducing New Ideas

Greetings, everyone, new to the forum and trying to get acquainted with the wealth of history and information here.

But aside from that, I had an interest in creating a character, specifically a Quincy, but with..quite possible a lot of liberties, many of which include other organizations of quincy, and tying it into history as well. Not to mention a possible metamorphosis into different states of being. Am I allowed to introduce anything new or can I just do whatever within my own profile?
