Marlenx was deployed to Nessus during the Red War and was assigned alongside several other Lightless Guardians to aid in a operation to infiltrate the Vex complex known as the Insight Terminus to discover what the Red Legion were doing there. She disliked the assignment and was worried about how without the Light she could die her final death, causing her to wonder why she was even there. She heard footsteps below her, and as she prepared to open a door down she heard movement behind her. Swiftly turning, Marlenx spotted a wounded Guardian entering the hallway without a weapon. Realizing that this was her purpose to be there, she gestured to the wounded Guardian to remain where they were and proceeded through the door and breaking off the door handle once on the other side. Marlenx then settled into position on the stairwell and awaited her foes, determined that nothing would get past her to the wounded Guardian.
