Personality: To start out, Garnet has a tendency to put the world's weigh on her shoulders, and often blames herself for events she cannot control. This tendency once caused her to sink into a deep depression and to stop speaking after the Invincible destroyed Alexandria. She's shy and soft spoken, and often relies on others, seeking their help, relying especially on her friends. She seeks the power of the Eidolons to protect Alexandria and her friends.
Through Zidane's influence, Garnet learns to act in a more regular way, and she wishes to "blend in," changing her speech patterns over time from overly formal to more casual and natural. Garnet can be a little naive at times, perhaps due to her sheltered life within Alexandria. Despite this type of upbringing, Garnet is quick-thinking and finds ways to outwit others in order to pursue her goals.
History: Garnet was born under the name of Sarah in Madain Sari, where she was part of a Summoner tribe. Like all Summoners, she had a horn in her forehead. Garnet and her mother escaped Madain Sari by boat when Garland attacked the village with the airship Invincible. The boat was destroyed, and her mother was killed.
Garnet washed ashore in Alexandria where she was discovered by the King. She looked almost identical to the real Princess Garnet, who had died not long before from illness, with the exception of the horn. The King ordered her horn removed and that she become a "replacement" princess. She was then raised as the Princess of Alexandria, and always thought Queen Brahne was her mother. Pluto Knight, Adelbert Steiner, is ordered to protect her.
After the King's death Queen Brahne begins to change. Garnet is worried about her mother and wants to seek aid from her "uncle Cid", the regent of Lindblum, but knows her mother would never let her leave the castle alone. Thus the princess seeks to escape from Alexandria. Her chance comes on her 16th birthday when the theater troupe Tantalus comes to Alexandria to perform I Want to Be Your Canary. Unbeknown to her, Cid has already asked Tantalus to kidnap her. She goes along with this plan and joins with Tantalus as they escape Alexandria. In the middle of the escape, Steiner is taken along with her. The Tantalus Theater Ship is badly damaged by a Bomb and they crashland into the Evil Forest and Steiner works with the Tantalus kidnappers to save her from the monsters within the forest.
After escaping the Evil Forest, Garnet struggles to hide her identity as the Princess of Alexandria. As a precautionary measure before entering the village of Dali, she adopts the alias of "Dagger", taking the name from Zidane's weapon. Upon entering the village, Zidane begins to tutor her in "common speak", a task Garnet has difficulty with, often addressing the townspeople in an overly formal manner.
Cid refuses to take major action against the kingdom of Alexandria, and he and Zidane tell Garnet to remain in Lindblum for her own safety. Unhappy, Garnet resolves to visit her mother herself, using a feast to commemorate the Festival of the Hunt to her own means. Garnet poisons the food of everyone else at the table with Sleeping Weed, except for Steiner. She then drags Steiner along with her, and leaves for the South Gate. Along the way, Steiner is forced to hide her in a burlap sack in order to avoid detection, and Garnet uses the nauseous odor of Gysahl Pickles to discourage others from opening the bag, as an extra precaution.
Though the princess and her knight reach Alexandria safely, Garnet is betrayed by Queen Brahne, who orders the jesters Zorn and Thorn to extract Eidolons from her. The summons Odin, Atomos and Bahamut are later used by the Queen and Kuja as weapons.
After being rescued by Zidane, Garnet begins to have internal conflicts about her mother's trustworthiness and the Eidolons within herself. When the party's Gargant crashes at Pinnacle Rocks, Garnet meets the Eidolon Ramuh. She casts aside her fear of the Eidolons, and Ramuh becomes the first Eidolon she is likely to summon.
Garnet's roots in the summoning arts are further explored when the party ventures to Madain Sari on the Outer Continent. Eiko Carol shows them the destroyed village, and Garnet discovers her true past and birthrights. Though the two have a sort of rivalry over Zidane's affections, they eventually become friends and learn they are the last two summoners left. Garnet also finds out Eiko knows the tune to "Melodies of Life", so it may be said that the song had its origins in the summoning village.
At the Iifa Tree, Queen Brahne's attempts at dispatching Kuja with Bahamut backfire and he leaves her for dead on the beach. Garnet rushes down and attempts to comfort her adopted mother, but her efforts are in vain. Brahne dies on the shores of the Outer Continent, but not before she apologizes for her deeds and asks Garnet for forgiveness. Garnet then becomes the new Queen of Alexandria.
The festivities surrounding her coronation are short-lived; Kuja returns to Alexandria with the Eidolon Bahamut, who begins to destroy the city. Garnet joins with Eiko to summon the Eidolon Alexander, the protector of Alexandria, who defeats Bahamut, but Garland uses the Invincible to obliterate Alexander and much of Alexandria; the resulting shock renders Garnet mute, apparently guilt-ridden for failing to protect her kingdom. After escaping from Kuja's palace, Zidane finds Garnet in Alexandria, mourning at the grave of her adopted mother. Here, Garnet breaks her silence by resolutely telling Zidane she will fight for her country. She once again takes Zidane's dagger, and uses it to cut off her ponytail, perhaps seeing this as a way of moving on with her life.
After Necron's defeat Zidane apparently sacrifices himself to return to Kuja's body. Garnet returns to Alexandria to rule, but she cannot forget Zidane's absence. Sometime later, Tantalus once again comes to the streets of Alexandria, performing I Want to be Your Canary in honor of the Queen. The character supposed to be Marcus throws off his cloak at the play's climax, revealing himself to be Zidane. Garnet runs out of the castle into the crowd, losing her necklace in the process. Garnet runs towards him, throws her crown aside, and leaps into his arms in tears. The game ends with Garnet and Zidane embracing in front of the applauding Alexandrian crowd. She asks Zidane how he managed to return, and when he tells her he sang her song, she corrects him by saying, "Our song."
