Cecil (セシル Seshiru, fan translated as Cecille) is a playable character from Fire Emblem: Mystery of the Emblem and its remake. Initially a member of the 9th platoon of Altean knights, she later joins the 7th platoon. She dislikes losing, and often gets into fights with her fellow knights. After the war she remains with the Altean knights and cares for the survivors of the war. Until the introduction of Sully in Fire Emblem Awakening she was the only default female cavalier in the series.
According to the Takayashiki Hideo's Mystery of the Emblem novel adaptation, Cecil is 16 years old. 
Automatically from the start of Chapter 1.
- Roderick - 10%
- Cecil joins with an additional Steel Sword/Lance/Axe/Bow or Elfire tome in her second slot, depending on the Avatar's starting class, as well as a Steel Sword, Steel Lance and Steel Bow in her remaining slots.
Cecil has impressive speed and skill, but unlike Roderick has issues with strength and HP. Thankfully, her HP growth rate is as high as her Speed and Skill growth rates. In Shin Monsho no Nazo, due to said growths and her sword skill, the Myrmidon class is a good fit as a reclass, although she will also make a decent Archer. She will also make decent Cleric or Mage due to her magic growths matching that of default tome-wielding characters such as Linde or Etzel. However, she will have mediocre defense growth as a tome-wielding class in part due to her poor base defense growths.
New Mystery of the EmblemEdit
"Cecille devoted the rest of her life as a paladin of House Altea."
