The Seppun are a noble family within the Phoenix Clan, dedicated to serving the Emperor and ensuring the stability of the empire. They are protectors of the Emperor, responsible for safeguarding the imperial family and maintaining the honor of the throne. Seppun members typically receive training in various forms of combat and strategy, embodying the principles of Bushido and upholding loyalty and duty.
The Seppun's commitment to their roles was acknowledged during a gathering at a waystation on the border of the Kitsu Family and Akodo provinces, where the Emerald Magistrates, including members of the Phoenix Clan, discussed their duties. The magistrates emphasized the importance of justice, trust beyond clan divisions, and representing the Emperor's voice. Within this context, Bayushi Monban expressed a desire to study under the Seppun, reflecting respect for their skills in protecting the Emperor.
The gathering also included a ritual to honor ancestors, which led to a supernatural encounter with Matsu Tomoe, an ancestor of Doji Setsuna. This encounter underscored the weight of ancestral duty and the expectations placed upon the Seppun in maintaining the honor of their lineage and the Emperor.
