Ana

Ana is one of the main antagonists in Rise of the Tomb Raider. She appears early in the game trying to warn Lara away from her father's research, as she worries she's headed down the same self destructive path.

Ana was Lord Richard Croft's former girlfriend. In the game's optional dialogue audio files, Lord Croft explains how he met Ana. He was approached by her after a conference on folklore and anthropology. He was surprised to find her questions were "intelligent, almost innocent in their inquisitiveness".

He stated having Ana in his life "Put new wind in his sails". She displayed interest in his work, organized his research and eventually became his editor. He noted that "Her presence in the manor has revitalized everything".

Although Ana brought Lord Croft happiness, he believed Lara thought she was replacing Amelia Croft. However, in adult Lara's dialogue files, she states Ana made her father happy.

Unfortunately, much to Lara's disbelief and disgust, Ana is revealed to be working with Trinity, and is Konstantin's sister. Ana has been manipulating Lara's family for years, however, she still seems somewhat sentimental towards Lara. Because of this, she orders Trinity forces and 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. Ana needs the source due to a disease she has, though she contradicts her work when she carelessly lights a smoke.

After Lara escapes from the Gulag and joins forces with the Remnant people, Ana and Konstantin continuously argue over the fact that Trinity is only using them as the instruments to their triumph, and do not intend to let them keep the source.

Ana has also not only manipulated the Crofts, she has also let her mentally disturbed brother believe that he is carrying out God's will, and has been since they were children.

Mid game, Lara encounters Ana in the Cathedral where the Atlas (a map to the source) is hidden. Having no choice, Lara uses Ana as bait to the Trinity mercenaries, so that she can traverse deeper into the ruin. There she injures Ana and gains the upper hand to locating the source.

After the encounter in the Cathedral, Ana drops the sentimental feelings for Lara, believing that "she can break her".

In the end, Ana retrieves the source, however, Lara destroys it before she can use it. In a post-credit scene, Ana is seen to be alive, leaving Siberia with Lara. However, just as she is about to reveal the truth of Lord Croft's death, she is shot and killed by an unknown sniper.

Trivia

 * Ana is first mentioned in Issue 18 of the comic series. She apparently recommended someone for Lara to talk to about her experiences.
 * The fatal disease she suffers from is never revealed but it is hinted that it might be cancer, possibly lung cancer, given her frequent coughing, the fact that Ana is a smoker and that her brother Konstantin becomes alarmed when Ana lights up a cigarette at one point.
 * Like her brother but not as strongly, Ana is ruthless towards the Trinity sub-soldiers, not caring for their lives as they tried to find the Atlas, a map to lead them to the Divine Source.
 * Unlike Konstantin, her faith and trust towards Trinity isn't very strong. She knew that she was just an expendable tool to them and said this to her brother, foreshadowing the way she dies.
 * Ana is voice acted by Kay Bess, who had done much with narrating documentaries and voiced several characters in Dead Space.
 * Ana's last name is never revealed.
 * Ana wears glasses in the photo she took with Richard and Lara however she's never seen wearing them in game.
