Lyra was an average mare at first sight, but if you really got to know her, she would really creep you out. She studied the humans and read books about them, about when human and pony society were integrated. But those were a long time ago. Celestia seperated the ponies from the humans and they were not alowwed to interact with eachother and had to stay in areas like a big border where humans were on one side, and ponies were on the other. Celestia had the guard patrol this border and they eventually made a wall. This wall was made for better security. The parents had told their children about eachothers species and how they were animals. Played off that the kids were afraid of one another, not being interested in the other society. But there was Lyra. Her parents had excommunicated her on the fact that she was a psycopath. A xenophobe to be exact. She was OBSESSED with humans and their way of life. She even wondered how they had, well, you know. It's a sex thing. She tried to sneak past the gaurds at the wall and was arrested. Ponies just can't sneak correctly. Lyra gave up, for a while. She eventually decided to give up on it. She got herself into a relationship with a baker, Bon Bon I think her name was. The lived together and had great relationship. The two were very intimate with eachother, and Lyra was the one who "wore the pants in the realationship". But she still secretly studied humans, occasionally "really thought" about them. She was absolutely obsessed, but enough about that.
Her dream was about to come true, though.
