  Summary

  There's more than one way to prevent someone from becoming a threat - especially for a queen who's grown too indifferent to care about her methods. But what about her past self?

  A story in which Castoria meets Tonelico before the tragic fate befell Orkney, and joins the future savior on her pilgrimage - unaware Tonelico is the future queen Morgan.
