Prior to the ' s first encounter with the Borg , the Federation had knowledge of their existence , based on encounters with surviving members of species that had been destroyed by them such as the El - Aurian s .

After tracking stray readings and sensor echoes for eight month s , the Hansens were able to locate a Borg cube . The " Raven " trailed the cube , following it into a transwarp conduit all the way to the region of the Borg ' s origin , the Delta Quadrant . The Hansens designed new technologies to allow themselves to study the Borg more closely and prevent the Borg from detecting them . They developed multi - adaptive shield ing that made the " Raven " virtually invisible to Borg sensor s , and bio - dampener s to mask their bio - sign s while on Borg vessels . Magnus visited Borg cubes in person to observe first - hand the behavior and interactions of Borg drone s . He and Erin also transported regenerating drones onto the " Raven " for study . The Hansens became very well - versed and comfortable in their endeavor , even giving them nicknames such as " " and " Needle Fingers .

Pursuit of the " Raven " began and attempts to escape them by masking the ship ' s warp trail failed . The Borg caught the ship and assimilated the Hansens and their daughter who later became known as Seven of Nine . The " Raven " itself was partially assimilated , but the Borg chose not to keep it , and it eventually crash land ed on an M - class moon orbit ing the fifth planet of a yellow dwarf star in the region controlled by the species known as the B ' omar . The Hansens ' field notes , contained in 9 , 000 - plus log entries , were retrieved in 2374 by the Federation starship from the wreckage of the " Raven " . ( ) Ultimate fate . The " Voyager " crew used the Hansens ' data in 2375 in their successful theft of a transwarp coil from a Borg sphere . In the course of this caper , Seven of Nine , who had been freed from the Borg , de - assimilated and become a member of the " Voyager " crew , was forced to surrender herself to the Borg under threat by the Borg Queen to assimilate " Voyager " .
