After Queen Brahne's death, Garnet is crowned Queen. During her coronation, Kuja attacks with Bahamut, forcing Garnet to draw out the legendary eidolon Alexander, who is summoned with the help of Eiko. Alexander destroys Bahamut, but Garland takes control of the Invincible and uses it to eliminate Alexander, destroying much of Alexandria with it. Succumbing to the recent traumatic stress, Garnet becomes mute in her depression until she can finally come to terms with her emotions late in the game. In this psychological state, she often has difficulty concentrating during battle, resulting in the occasional failure to perform actions such as White Magic and Summoning.
