The Orpheus Final Plan (オルフェウス最終計画, orufeusu saishuu-keikaku) is the master plan of Ouroboros. The plan is drafted by the Grandmaster. The goal of the plan is currently unknown, but according to Anguis Vita Clotilde it involves guiding "the souls of all".[1] In order to achieve their goal, the plan involves the recovery of all seven Sept-Terrion.

The Orpheus Final Plan is divided into multiple sub-plans centred around the recovery of one or more Sept-Terrion.

List of sub-plans


  • During the development of Trails in the Sky The 3rd, there the Orpheus Final Plan would follow after completion of the Gospel Plan. In the final version, the Phantasmal Blaze Plan was introduced as the next step toward the completion of the Orpheus Final Plan.
  • In Greek mythology, Orpheus is regarded as a musician capable of charming all living and even inanimate things with music. He is best known for his attempt to retrieve his wife Eurydice from the underworld. It is unclear whether the Orpheus Final Plan and the Greek mythological Orpheus are related.
