Sagira

Sagira was the Ghost who belonged to the legendary Warlock Osiris. She appeared in the expansion Curse of Osiris, acting as a guide to the Guardians.

Because Panoptes, Infinite Mind could see Sagira and her Light, Osiris had to send her out of the Infinite Forest for her own safety and to keep himself hidden from Panoptes’ gaze. Sagira was wounded by a Vex blast as she returned to Mercury, where she was found by one of The Hidden and brought to Ikora Rey. Ikora gave Sagira to the Guardian, who attempted to fix her by bringing her to a temple hidden deep within the European Dead Zone. Sagira was placed in a device that fused her consciousness with Ghost, allowing her to temporarily use his body as she guided the player through the Infinite Forest, until her capture by Panoptes.

After Panoptes’ defeat, Sagira returned to Osiris as they bade Ikora and the Guardian farewell.

Eventually, after the Guardian deployment to Europa, Osiris and Sagira had begun investigating the Cryptoliths that had appeared around the solar system. When Osiris encountered and was nearly killed by the High Celebrant of Xivu Arath, God of War, Sagira had sacrificed herself to save Osiris, leaving him Ghostless.

Defending the Last City
As time went on, Osiris and the Speaker became close, with Osiris becoming the Speaker's apprentice, as the Speaker saw Osiris grow weary of ordering countless missions and dealing with the cryptarchs. Osiris' became increasingly interested into the investigations of thanatonautics, Ahamkara-lore, Xûr and The Nine, as well as his questioning about the nature of Ghost reincarnation and the Traveler's motives.

Exile
Osiris began diverting Vanguard resources in his quest for answers, including launching an expedition to the Reef, and influencing other Guardians to abandon their duties in the City to pursue the same questions, which often led to their deaths. The Speaker decided to act after determining that Osiris had created a cult of personality around himself. After the Battle of the Twilight Gap, Osiris was exiled for his growing obsessions, particularly with the Vex, and misuse of Vanguard resources. During a meeting of the Consensus, the Speaker officially announced the exile and appointed Ikora Rey to take over as Warlock Vanguard and Commander Zavala as Vanguard Commander, with none of the Consensus objecting to his decision. Osiris and his followers, now known as the Cult of Osiris, left the City and disappeared across the solar system.

Osiris was eventually spotted in the Caloris Basin on Mercury and was investigating the Vex and the Speaker dispatched Saint-14 to stop their former friend. Osiris had entered the Infinite Forest, a Vex machine designed to predict and simulate reality.

The Infinite Forest
Osiris was mapping out new paths in the Infinite Forest when he eventually discovered the tomb of Saint-14. The Warlock mourned the loss of one of the Last City's greatest heroes, but most importantly, his old friend. Electing to leave him within the tomb the Vex constructed, The Young Wolf recovered the 'Perfect Paradox' shotgun from Saint-14's corpse, along with the letter written to them. Osiris became devastated upon the demise of his old friend, and true to Saint's prediction, blamed himself for the valiant Exo's death. At a later time, Osiris visited Saint-14's tomb with his Ghost Sagira for examination. Noting that there was no fatal blow or damage on the Titan's armor, The Warlock wondered if the Vex had repaired it. They both discussed the ribbons that Saint-14 had called his "accolades", and Osiris sadly stated that he'd never asked his friend what they were for.

Continuing to study the different realities of the forest with little, yet newfound determination, Osiris and Sagira spent years studying different realities that the Vex were simulating. During one of their expeditions, they arrive at a frozen Vex-simulated fight against a fireteam of Guardians inside the Vault of Glass. While Osiris worked to reconfigure his cube-like artifact, Sagira moved some of the Vex's weapons to point at the sky instead of the Guardians, making a joke about "reaching for the sky". Sagira, turning back to check on her Guardian, begins to feel concerned towards him, as the Infinite portal the Warlock constructs and observes fills him with fear. In a short moment of time, the Vex begin to move again and attack Osiris and Sagira. One by one, Osiris cuts through the small army of Vex and quickly smothers them in flames with his Daybreak super. Without hesitation, Osiris then activates another Infinite portal, urging Sagira towards it saying she has to warn the Last City. Taking matters into his own hands, Osiris throws his reluctant Ghost towards the exit before a Vex Goblin's slap rifle bullet fires off and hits the side of her shell. The damaged Ghost was later discovered by one of The Hidden agents and was eventually brought to Ikora.

Broken Time
Sometime following the death of the Infinite Mind and the discovery of Saint-14's remains, Osiris began pooling resources from the Infinite Forest. With the Drifter's consultation on its engineering, Osiris created a prototype of a time-traveling device, The Sundial, with the intent of saving the fallen Titan from his final fate. Using a dozen of his Echoes, Osiris scoured throughout the history of Mercury for the moment where Saint fell to the Martyr Mind, but was unsuccessful in his attempts at locating the right time span before giving up and shutting down the Sundial in disappointment.

When three Psion Flayer sisters from the Red Legion hijacked the Sundial and began fragmenting Mercury into multiple alternate timelines, the Guardian took up the seemingly impossible task of rescuing Saint-14 from his fate much to Osiris' bitter skepticism. Using a unique frequency keyed to the Perfect Paradox that they recovered from Saint's personal effects (after it had in fact been created by the Guardian at the Infinite Forge on Mercury), the Guardian and their Ghost traversed time to an early moment in Mercury's past, during Saint's first off-world mission. Upon aiding the Exo in a fight against Fallen from the House of Rain, the Guardian gifted Saint with the Perfect Paradox, and their Ghost shared a vision of the present-day Last City; this act would inspire Saint to become the hero he is remembered as in the present.

Days later, Osiris discovered a distress signal from Saint's Ghost in the Vex network, and dispatched the Guardian to Nessus to open a gateway into the network and find it. The Guardian located the dead Ghost held by a broken Goblin atop a pile of dead Vex, and heard Saint's last moments before he is killed. With the Ghost as a guide, the Guardian again used the Sundial, this time managing to arrive at the proper moment in time. They come across Saint amidst the wreckage of several Vex, his Light already drained by the Mind created to stop him: Agioktis, Martyr Mind. Together Saint-14 and the young wolf defeated the Martyr Mind and Saint emerged from the forest, smashing through Descendant Vex, ending with a Minotaur that he headbutted to death in the same fashion as he had killed Solkis at Twilight Gap.

A Bright Light Extinguished
Osiris and Sagira had begun investigating the Cryptoliths that had appeared around the solar system. When Osiris encountered and was nearly killed by the High Celebrant of Xivu Arath, God of War, Sagira had sacrificed herself to save Osiris, leaving him Ghostless. Her death played hard on Osiris, becoming the catalyst to him being possessed by the Witch Queen.

"She can help us one last time, and then we can bring her home."

- The Ghost, after recovering Sagira's remains

Sagira's remains were recovered by Savathûn and placed within the depths of the Temple of the Wrathful in her throne world, which was dedicated to the Witch Queen's sister Xivu Arath. The Ghost Fynch learned of her shell's location during his brief time with the Lucent Brood and informed the Guardian of her location during their investigation into how Savathûn acquired the Light. Sagira's shell was recovered by the Young Wolf after they slew Brutiks, Lightbane, a Scorn commander who had claimed the temple as his lair. Upon recovering her shell they experienced a brief glimpse into a memory of Savathûn that was left behind as a psychic imprint. In order to view the memory fully, the Young Wolf sought out the Alter of Reflection within the throne world. Placing Sagira's shell on the alter, the Young Wolf was able to listen to a memory of the Witch Queen which discussed her plan to infiltrate the Last City while posing as Osiris and revealed the existence of The Witness to the Vanguard.

Trivia

 * Sagira was the first Ghost to appear radically different from those partnered with the Guardians, and was also the first Ghost other than the player's to be voiced.
 * The name Sagira is Arabic for “little one.”
 * Sagira was the first confirmed female Ghost to appear in-game. Eriana-3's unnamed Ghost was also female, but appeared only in Grimoire. The player's Ghost mentions that Cayde-6's Ghost was female as well.
 * The player's Ghost and Sagira don't exactly get along well as she "borrowed" his Guardian and used his body. He calls her "Guardian thief" on one occasion, and gets very defensive when Sagira idly suggests that they team up again. On one occasion, when the two actually agree on something, Sagira is disconcerted by this.
 * Sagira initially expressed dislike for Ikora as she led the group that exiled Osiris but admits that the people were not ready for what he had to say. She later expressed admiration when Ikora came up with the idea of looking into the past to find Panoptes, declaring that the idea was "Osiris-level good". Sagira was happy that she, Osiris, and Ikora were able to be friends again.
 * Sagira was voiced by actress Morena Baccarin.
