Born on Palaven and a decorated engineer in Blackwatch, Macen Barro was touted by the Hierarchy to be a shining example of a turian citizen. There were concerns among Initiative leadership about whether or not he would leave his comfortable life behind to become the turian Pathfinder, but Macen was eager—so long as he could name his replacement: Avitus Rix, a former Spectre. Internal emails and screening interviews state Macen and Avitus met in the field and suggest that their relationship may be more than platonic.
Macen Barro left the Milky Way aboard the turian ark Natanus in 2185.
With Macen Barro dead and Avitus Rix refusing to take his place, the turians find themselves without a Pathfinder. The Nexus continues to search for a replacement, but with survivors from the Natanus scattered across the Heleus Cluster, it will be take time to fill the role.
