Sasha

"Here's the relic, my love. I hid it like you asked. Father's grown suspicious of us, but that won’t matter once we're married. It won’t be long, right?" "Of course, my dear! Soon we will settle down to a quiet life of tilling the fields and raising brats...uh... children. But first I have to sell this relic! Alas, I must travel away with my friend here to do so."

- Sasha and Lyndon

Sasha is a peasant farmer girl encountered as an NPC in of Diablo III.

Biography
"After much searching, I have found a promising lead. A family near New Tristram has obtained a valuable relic, and poor fools that they are, they haven't the slightest idea what to do with it! I have some idea of what to do with their daughter, though...and through her, I'll get my prize."

- Lyndon

Sasha and her family lived on a farm near New Tristram.

At some point prior to meeting The Nephalem, Lyndon met Sasha, purposefully seducing her in an attempt to recover a valuable relic from her parents. Promising her marriage, he convinced her to not give the relic away. However, the Thieves Guild eventually found Sasha and threatened to kill her, as they were pursuing Lyndon and/or the relic he coveted.

At this moment, with the help of The Nephalem, Lyndon saved Sasha (and the relic), and immediately departed with the intention to sell the item (as he explained to Sasha, to get money for their wedding). Moments after leaving, he realized that the relic was a fake. When The Nephalem asked Lyndon about his betrothed, the Scoundrel replied that he was not the marrying type.
