Claes Celestia Misca Sancest (クラエス・ホシヒメ・ミスカ・サンセスト, Kuraesu Hoshihime Misuka Sansesuto?) is a supporting character from Final Fantasy Type-0, and is voiced by Nana Mizuki. According to the Crimson Codex, Celestia is 32 years old and 135cm tall.
Celestia is a l'Cie of the Sōryū Crystal from the Kingdom of Concordia, her memory restored by Andoria whom she serves as her right hand. She is an elite knight of the Akatoki, who protect the kingdom's Peristylium and Andoria. She is very prideful regarding her nation. During her visit to the Suzaku Peristylium early in the game, she runs into Deuce and asks her for directions.
Later, when Andoria is secretly murdered by the Milites Empire, Celestia accuses Class Zero, wrongly believing that her queen's death was caused by them. Summoning Bakurairyu to knock out Rem Tokimiya and Machina Kunagiri before focusing it on Ace, Celestia cancels her attack when Deuce bravely convinces her to stop and instead give them safe passage outside the city.
After the Concordian King offers his services to Cid Aulstyne, the real mastermind who secretly plotted Andoria's murder, Celestia is sent to lead the Concordians' assault against the Rubrum military as part of Milites's two-pronged attack. During the battle, informed of Rubrum gaining the advantage, Celestia assumes her Shinryu form to kill off the Class Zero members assigned to the fight. However, Arecia Al-Rashia intervenes with the summoned Bahamut-0 driving Celestia back.
Eventually, being the only remaining l'Cie in the world, Celestia goes against the Sōryū Crystal's design and helps Class Zero reach Cid as he invokes Finis. Though part of her cannot forgive Class Zero, Celestia also knew that Andoria had seen her death and followed through with it out of hope. After leaving Class Zero with the parting words that they should not fear death and follow their own path, she assumes her Shinryu form to fly ahead of them to avenge Andoria. However, Celestia dies when her Phantoma is absorbed by the newly transformed Cid with her crystallized body sent falling into the abyss below the site of the final battle.
Though she can summon dragons to fight her battles, Celestia can use her l'Cie powers to transform into Shinryu Celestia. With the right amount of skill it is possible to defeat Shinryu Celestia without having to resort to Bahamut Zero.
Celestia appears in the Final Fantasy Trading Card Game on two cards: depicted with he official render with the Concordian flag in the background, and with an artwork of her. The cards are part of the "Aqua" set.
