Okay, I have three races in my book, two of which I think I have sorted out (aka: humans and Shifters) but I keep running across different scenarios and ways that I can make my book simpler by changing the background of the third race. Let me explain: this race is known as the Imirri, and look perfectly human other than their eyes, which are always gemstone or metallic in color. They also can tap into powers over weather, ice, pressure, gravity, and on rare occasions time. This race plays the role of being the protector of the human race from the Shifters. The book takes place after the Imirri has supposedly died out, but the main character discovers that she is the last of their kind. Now, here comes the issue. The Imirri could work two ways: One, they could be a mysterious magical people from a distant land of mists called the Ether, or: Two, they could be a race created by humans casting a powerful spell and giving up their own magic to make special guardians during the war. I can do both very easily, but I haven't quite chosen on which one yet. Now I know this isn't much of a question, but can you guys help me pick which one? Even this tiny detail will end up changing part of the MC's journey, and I want to make sure it makes for good reading.
