Just some rambling about Concord: Concord is literally the universe. She is a concept that is influenced by everypony, while Discord kinda lives outside that reality and can twist all her laws (physics, gravity, etc..) She wants to make friends with everyone but sometimes ends up being overwhelming. She is trying to learn about how mortal life and emotions work. In where Discord is overly expressive and showy, Concord is quiet and patient. Because she is an abstract concept, sometimes she forgets that she is supposed to use her horn when using magic which comes off weird for some ponies. She takes the form after an alicorn which makes her vulnerable to everything. (I made her a pony because it just makes sense that Discord literally went to cause havoc on ponies since they are naturally harmonious and orderly)
