Bonds of Gold BoG

Who is Esper Vallispear and why did he take Luna Lovegood? The Hogwarts staff struggle to find answers, all the while dealing with Harry and the golden trios shenanigans.
This is mainly a Esper x Luna story, but I don't want it to appear to mainly focus on romance. I plan to expand by quite a bit so everyone can find something they'll like about it. Also, this won't be Harry centered, although it will play elements.
