A threat is forming in the underbelly of Equestria., a threat who's true nature remains disturbingly elusive to Equestria's Night Princess.

With her millennium-old confidants long dead and gone, the newly-returned Princess Luna calls upon a dangerous but loyal ally to gather the ponies she needs from her sister's unfamiliar Equestria. Together, they seek out the underdogs and the overshadowed, the second-place and the unappreciated, those who's virtues are not so readily visible in the light of day. Ponies among whom she has much in common.

They are not like the Element Bearers.

They are no heroes.
