Camus

Camus (also known under the aliases Zeke and Sirius) is the leader of the Black Knights Squad from Grunia. Despite his liege's decision to ally with Doluna, he obeyed his country and fought for its honor. He also protected Nyna from Akaneia and sent her to Orleans, also falling in love with her. Unfortunately, he eventually encountered Marth in battle and was thought to be dead in the ensuing battle.

In reality, however, he survived, and lost most of his memories and ended up in the continent of Barensia, where washed ashore and was found by Teeta, a saint working under Rudolf I. In a years time, "Zeke" (the name was given to him by King Rudolf) rose to become a high ranking general in the Rigel army, but was oppossed the war, which led to Teeta being captured in order to force him to fight. When he learns that Teeta is safe and after he notices a mark on Alm's right arm, one that belonged to the person who would save Rigel, according to Rudolf, he joins Alm's army. After the war he lived a happy life with Teeta and recovered his memories, although he did not tell her this.

He would live with her until the following year, where he heard of Hardin's ascension to throne and fall to madness, at which point he took up the identity of the masked knight Sirius and returned to Akaneia. He first appears to Ogma when the latter was protecting the Grunian royal children From Medon's Vikings, and is asked to join the Altain army fighting Lang, the corrupt leader of Akaneia's occupational army. While he notes that he is not promising anything, he joins the army once the Vikings are defeated. Later on, due to his true identity, he was able to snap Nyna out of her mind control from Medeus despite denying to her that he is Camus. She protests, but he states that she is tired and should return to Marth's side, followed by a apology which she overhears. After the war he vanished, claiming to Nyna that he was returning to his country and that someone was waiting for him there.

Camus is playable in the Satellaview SNES game in a mission where he must protect Nina with help from Grunia's Black Knights. He wields the legendary lance Gradius. He is also playable in Fire Emblem Gaiden as Zeke and Fire Emblem: Monshō no Nazo as Sirius.

Aliases
It is never mentioned directly that either Sirius or Zeke are actually Camus. According to Gaiden's official timeline, Zeke shows up on Barensia the same year as Camus's "death" and leaves the same year as Sirius's "introduction", as well as his only memory when arriving in Barensia was that he was fatally wounded in battle. As for Sirius, he outright denies being Camus to Nyna, however mutters a apology to her as he leaves, which she overhears.
