Twilight knew the day would eventually come, the day that Spike would move out to live his life. As he had become of age Rarity had accepted his feelings and after a few years they were to be wed.
Twilight thought she could handle things on her own, but she had become so accustomed to having someone by her side to help her. After taking a walk through the now tame Everfree Forest she comes across a strange being in a tux. This being is the solution to her present problem.
Little does she know, this being isn't just in Equestria to find someone to serve, it's on the lookout for something that could be a danger to all living things.
This is not a human X pony fic, the romance tag is for something else further down the line
