When what starts as an attempt on Princess Luna's life becomes a mad grab for power, Celestia must call upon her most skilled weapon, the Paladin. Cheerilee is an ordinary school teacher with a very unorthodox side job. Will her training in the ways of justice, and honor be enough to stop the threat against Equestria? Along her journey she will make new allies, gain new strengths, and become more personally involved then she ever would have imagined.

Note: As for the tags it is only slightly dark and only slightly sad, and not grim-dark at all (more light-dark sometimes). It is Adventure first.
