Maps and Legends

Hoping to find Soji before the assassins get to her, Picard investigates Dahj's apartment with his Romulan employee Laris. The latter believes the assassins may be members of the Zhat Vash, a secretive organization with a deep-rooted hatred of synthetics, and helps Picard discover Soji's location from Dahj's computer. On the Borg Cube, called the "Artifact", Soji develops a relationship with Romulan agent Narek while she works on a project to remove Borg technology from former Borg drones. Despite the onset of a terminal illness, Picard asks Starfleet Admiral Kirsten Clancy for a ship and crew to find Soji. She refuses him and refers the incident to Starfleet's security chief Commodore Oh, who discusses it with a lieutenant who is Narek's sister Narissa in disguise. Narissa led the assassins to kill Dahj while Narek is approaching his target, Soji, with seduction rather than violence.
