Micene di Sagitter, originally named Aiolos, serves as the Sagittarius Gold Saint. His defining act occurred thirteen years before the main narrative: rescuing the infant Athena (Saori Kido) from Gemini Saga, who murdered the legitimate Pope and seized control of the Sanctuary. Fleeing with Athena, Micene faced opposition from Gold Saints Aphrodite of Pisces, Deathmask of Cancer, and Shura of Capricorn. Shura inflicted fatal wounds. Mortally injured, Micene entrusted Athena and his Sagittarius Gold Cloth to Mitsumasa Kido before succumbing near the Parthenon; his body was never recovered. Micene's legacy centers on a message inscribed within his Ninth House temple, revealed when the Sagittarius Cloth strikes the wall: "Giovani cavalieri che qui siete giunti: dono a voi la cura e la salvezza di Atena" ("Young knights who have arrived here: I entrust to you the care and salvation of Athena"). This inscription acts as a spiritual testament and guide for Athena's future protectors. The Cloth retains a connection to Micene's spirit, autonomously aiding the Bronze Saints during critical battles, including Seiya's confrontations with Phoenix Ikki and the Silver Saints. He is the older brother of Leo Aiolia, whom Micene personally trained in their youth, instilling principles of self-confidence and justice that profoundly shaped Aiolia. Their fraternal bond resurfaces during the Hades arc when their spirits reunite. In *Saint Seiya: The Hades Chapter - Inferno*, Micene's spirit participates at the Wailing Wall (Nageki no Kabe), the barrier between the Underworld and Elysium. Alongside other deceased Gold Saints, he contributes his cosmos to generate a collective light equivalent to the sun. This unified effort breaches the wall, enabling the Bronze Saints to advance toward Elysium and rescue Athena. During this sacrifice, Micene directly addresses Seiya and Shun, reiterating the trust from his temple inscription. Expanded media like the manga *Episode G* depict his escape, highlighting his reluctance to defend himself against Shura or Sanctuary soldiers, viewing them as misguided rather than enemies, emphasizing his commitment to minimizing conflict among Athena's forces. In the ONA *Soul of Gold*, Micene briefly returns as an Einherjar in Asgard. Alongside other Gold Saints, he battles the god Loki, achieving a God Cloth evolution for his Sagittarius Cloth during this conflict. Micene's influence extends beyond physical appearances. His armor repeatedly manifests to protect Athena's warriors, and his testament within the Ninth House serves as a moral compass for the Bronze Saints, solidifying his role as a symbol of righteousness and sacrificial loyalty.
