Visas Marr is a Miraluka, and although she is blind she is of a very rare, and special species of humanoid. She was able to rely on a force power know as force sight, with that power she was able to see. She was born on 3.976 BBY (Battle of Yavin). In approximately 3.952, her homeworld Katar hosted a secret Jedi Conclave in the wake of the first Jedi Purge.
By accident one of the Jedi's known as Atris, who was to attend the special event leaked out to much information. After which an evil Sith Lord known as Darth Nihilus came to take all life away from the planet, he was drawn there from the Outer Rim, unable to ignore the chance to consume the power profusion that the planet represented with some of the most powerful Masters of the Jedi Order assembled on a world as rich in the Force as the Miraluka's.
Visas Marr, when returning to her planet Katarr, saw all the extreme destruction, devastated she had so much pain that it was unbearable for her to take it. Nihilus, seeing that see was at her most vulnerable stage took her in showed her the ways of the Force and she later became his apprentice.
Her attraction to his power led her to the dark side. She was a very talented Sith Lord and did everything that Nihilus ordered, although she has stated this to the Exile, "My life for yours." It is believed that she said the same thing to her master. Only a year later both Visas and her Master felt a disturbance in the force.
The disturbance was no one else but an exile who was once again trying to retrieve his old ties of the force. Little did she know that The Exile would later be her destiny, either in life or death.

The Exile was a Jedi whom participated in the Mandalorian Wars, and because he participated he was outcast. Later in life he was known to be found on the Ebon Hawk, the dark Sith Lords were aware of his presence there and attacked the ship he was in. Visas was then sent to the ship and order by Darth Nihilus to kill and destroy this Exile.

Star Wars: Knights Of The Old Republic 2
One of the more common questions, especially if you've played Kotor 2, is was she and the Exile in love? Although there is no definite answer, there are some who say they were and others who say they weren't. In the game, If the player is using a male light-side character, despite some turbulence, he can eventually fall in love with her—which will, if the player is not careful, make him lose influence with Brianna.
Technically, however, it is not possible to have a romance with Visas Marr. If the Exile is male, Visas—like Mical if the Exile is female—will come to the Exile and proclaim her love for him. This, however, is different from the romance in the first KotoR game, where the player's character is able to return those feelings.
The same is true with the romance with Brianna. Though she reveals her name and she is, ironically, supposed to be a romantic interest, she does not state her love for the Exile or vice versa. So in conclusion the answer is up to you. Where they? "My life for yours.".
