I must say, as a complete newbie at critiquing histories, I'm not quite sure what to look for in a good history. However, personally, I really like Errare. (Rp with me sometime, maybe? ) My only issue would be that, although you are entitled to your own crack pairings/fan shippings/whatever you want to call them, I'm not too keen on the idea that she is the daughter of Discord and Pinkamena. Also, could you elaborate on how exactly that dimension changed her eye color?
