Sephiran

Sephiran was once known as Lehran, the thousand year-old heron who supported the Three Heroes in their fight against the Dark God Yune. It was thanks to Lehran's suggestion that the Goddess Ashera decided to seal Yune within the medallion that would one day be known as the Fire Emblem, rather than erase her entire existence. In exchange, he, along with others, took a vow that there would be no war for a thousand years. The plan was that, after that period, and should both Beorc and Laguz follow through on the promise, Ashera would become one with Yune again, forming the original goddess of creation, known as Ashunera, or the Goddess of Dawn. At the onset of the Mad King's War, Sephiran set out to observe the state of affairs in Crimea, in the guise of a simple monk. During his travels, he arrived in a small village and found Brom and Nephenee, who had been injured in combat, and worked to heal their injuries, but for doing so, he was captured by Daein forces and imprisoned in Canteus Castle. He was scheduled for execution by the Daein forces, but was released a day before his execution date when Ike and the Greil Mercenaries led an assault on the castle to free its prisoners. After a conversation with Ike he left, and it was not until his arrival in Begnion that Ike learned from Sanaki of his identity as the prime minister. At the conclusion of the war, Sephiran arrived in Melior and met with Ike following Ashnard's defeat, where Ike told him of his (erroneous) findings about Ashnard's role in assassinating Misaha and causing the Serenes Massacre, had Mist pass on the galdr of release to convey to Sanaki, and in return Sephiran informed him of the identity of the "Altina" he sought, Sanaki. Bitter from centuries of witnessing human cruelty—specifically the Serenes Massacre—he orchestrated major conflicts across Tellius, including the Mad King's War, to hasten the awakening of the goddess Ashera for a final judgment of the world.
