Oriana Lawson

Oriana is Miranda’s sister. She is seen during Miranda’s Loyalty mission.

Mass Effect 2
Oriana was grown by Miranda's father when she was just a teenager. Seeing that her father wanted to replace her in his plans for developing a dynasty, Miranda took Oriana to Cerberus. She was adopted and was given a normal life.

In 2185, Oriana's father paid Niket to find and retrieve her. Niket tracked her down to Illium, and used the Eclipse mercenary group to try and bring her back. Accompanied by Commander Shepard, Miranda prevented the Eclipse from capturing Oriana. At the end, Shepard can suggest that Miranda go up and talk to Oriana. If she does so, Oriana will later send a message to Shepard thanking the Commander, asking that Shepard doesn't tell Miranda she sent the message, and for Miranda to stop reading Shepard's mail.

== Mass Effect 3 By 2186, Oriana's father, now known as Henry Lawson, captures her after reaffirming his support for Cerberus. Miranda became aware of her disappearance and reached out to Shepard for help. Oriana was discovered on Horizon, where her father was conducting experiments on hapless refugees, turning them into husks or indoctrinated them to discover how to control the Reapers. Henry holds Oriana hostage when her sister and Shepard come for her. Though Shepard manages to convince Henry to let her go, Miranda was not interested in bargaining with him and defenestrated her own father.
