Ana

Ana is the main antagonist in Rise of the Tomb Raider.

She is a senior agent of Trinity who seeks the Divine Source, though she seeks it for herself, and not for Trinity.

She is the older sister of Konstantin.

History
Ana and Konstantin were raised by Trinity. At some point during their youth, Ana cut Konstantin's hands with a knife while he slept, to represent stigmata. Konstantin believed that the marks appeared by God's will as a sign that he was his chosen warrior.

As an adult, Ana began working for Trinity, as an assassin, and spy.

Getting close to Lord Croft
Ana was tasked by Trinity with getting close to Lord Richard Croft, a formerly acclaimed archaeologist, whose research was of interest to Trinity, though it was in their best interest that the public not be told about it.

Ana approach Croft at a conference he was speaking at. He was surprised to find her questions were "intelligent, almost innocent in their inquisitiveness."

After a while, Ana began a romantic relationship with Lord Croft, who later introduced her to his daughter, Lara on the suggestion of his butler, who thought Lara could do with a female role model, due to her tomboyish behaviour.

After Lord Croft discovers Trinity are onto him, they order his execution. Ana is unable to perform the task herself, as she had fallen in love with Croft despite the foundation of their relationship being a lie. Someone else committed the deed, and Croft's death was staged to look like a suicide, his body was discovered by Lara.

Some point after this, Ana is diagnosed with a terminal disease (presumably lung cancer.) This causes Ana to become desperate to find the Divine Source, however, Trinity cannot locate it and keep hitting dead ends. Ana realizes that the only chance she has is in Lord Croft's research, but Lara is the only one who would be able to decipher it.

Monitoring Lara
Years later, Lara resumes her father's research into the immortal soul, after finding evidence of it first hand, whilst on an expedition to find the lost kingdom of Yamatai. Ana reaches out to Lara and recommend a therapist for Lara to speak to about her experiences, secretly having all their sessions recorded.

She subtley manipulates Lara into continuing her father's research, through reverse psychology, though she worries Lara's frein

Ana goes to Lara's apartment one night to try and learn more about her father's research. She leaves via the fire escape before Lara arrives, and makes her way back inside to speak to Lara, almost being attacked by Lara in the process. Lara informs her that she has found the tomb of the Deathless Prophet, in Syria, hopefully to find the Divine Source, an artefact which apparently holds the power to grant eternal life. Ana tries to persuade her to go home. Lara ignores her and goes to Syria.

One of Trinity's goons, finds that Lara has found a link between the Prophet's tomb in Syria and the lost city of Kitezh, in SIberia. Ana heads out with Konstantin and a battalion of Trinity's forces. After arriving in the area, she ordered the capture and interrogation of the residents of the area including their leader.

Some time later, a sentry caught Lara and managed to knock her out. Ana concocts a plan to trick Lara into revealing the location of the Divine Source. When Lara regains consciousness, Ana feigns terror, before Konstantin comes in with a fibre wire and begins choking, Ana. When Lara states she doesn't know where the Divine Source is, Ana calls of Konstantin, Lara is horrified upon the revelation.

Ana offers Lara a position at Trinity, but is refused outright. She orders Konstantin to keep her alive for the time being, though this is much to Konstantin's dislike as he believes Ana's dwelling in the past will hold them back in their pursuit for the Divine Source.

A short time later, Ana and Konstantin are going over the local settlements, Ana orders a battalion be sent to raid a village nearby, unaware that Lara and Jacob had escaped and were eavesdropping on them.

The alarm is raised when Lara and Jacob's escape is discovered. Ana sends out the troops to recapture or kill her, though they are unsuccessful.

Trinity's invasion is mostly unsuccessful, though they are made aware of a map, known of the Atlas that can lead the way to Kitezh, and by extension, the Divine Source. Ana reminds Konstantin that if he fails, she will die. They manage to find out that the Atlas is located within the ruins of the old cathedral overlooking the remnant village.

In the Cathedral, Ana suervises the operation to recover the Atlas, sending several troops down to the lower levels where the are slaughtered by the Deathless. While overseeing an upper level of the cathedral, Ana is suddenly grabbed by Lara who uses her as a human shield to buy time, to improvise an escape plan, which involves blowing up the floor they are standing on. Killing all of the men in the area, though Lara and Ana are left dangling from rope, being weighed down by generators. Lara destroys the generators allowing them both to get to safety. Ana repeats her offer to Lara to join Trinity, however Lara retorts by shooting her in the shoulder, before storming off to retrieve the source. Ana orders her men to kill Lara and retrieve the Atlas.

After Lara gets the Atlas, Trinity sends a strike team to the observatory, to retrieve it. They are successful, retrieving the Atlas, and capturing Jonah. Ana and Konstantin manage to decipher the Atlas, and find the location of Kitezh, beneath the glacier. Ana leaves to mobilise their forces to prepare to break through the glacier.

The following day, Trinity are prepare to force their way through the ice, they manage to succeed raining down an massive amounts of debris on the city. Ana and a group of guards make their way to the chamber of souls, where she retrieves the Divine Source. Lara arrives and informs her that Konstantin is dead, and that more people will die if Trinity gets their hands on the Divind Source. Enraged, Ana reveals to Lara she has no interest in giving the source to Trinity. One of Ana's guards arrives and alerts her that they are surrounded by the Deathless, only to be killed by Jacob. Ana retaliates by shooting him several times, wounded, Jacob warns her that the source is not meant for the world, as it has wrought nothing but destruction.

Ana pleads with Lara to let her keep the source to save herself from death, adding that "Another Croft doesn't need to die for [it]." Lara adamantly refuses, stating she's willing to die in order to protect others. The Deathless close in, with no alternative, Ana unwraps the Divine Source and gazes upon it, as it begins to suck out her her soul, it overwhelms, her and she drops it. Lara destroys the source, ending the Deathless, as well as Jacob, leaving Ana with no possible cure.

Death
Ana leaves the crumbling city with Lara. In her weakened state, she stops to rest, Lara asks what Ana meant by "Another croft doesn't have to die for this." as Konstantin had revealed to her that her father was murdered by Trinity. Lara aims a gun at her and demands to know the truth. Ana confirms, that Trinity did order his execution, but she couldn't bring herself to do it, Lara accuses her of lying, Ana insists that she loved Lord Croft as she is shot and killed by an unknown sniper.

Appearance
Ana is an attractive woman, with blonde hair, and blue eyes, and pale skin.

As a result of her illness, the white's of her eyes are faintly bloodshot, and her skin becomes paler as the story goes on, being almost devoid of colour at the time of her death.

Personality
Ana portrays herself as a soft spoken and caring individual towards Lara, wanting what's best for her, and for her to not get mixed up in the work that consumed her father.

However, this is all a facade. Ana is a calculating individual who is an excellent manipulator, as she was able to manipulate her brother, who was a meek child into becoming a cold, apathetic killer who would stop at nothing to complete his mission, which he believed to be ordained by God.

Unlike Konstantin, Ana's faith in God is shaky, and she holds no illusions about being irreplacable to Trinity. As time goes on she becomes more and more desperate to save herself.

Like her brother but Ana is ruthless towards subordinates, not caring for their lives and seeing their deaths as necessary to sacrifices.

Despite all this, Ana did truly seem to care for Lara's well being, offering her a chance to join Trinity on multiple occasions. However she dropped any intention of keeping Lara safe after she was shot by her.
