Eternal Alliance operatives under Theron Shan eventually discovered Semhess and her project and a strike team was dispatched to X7-Cratus to stop RS-33 from becoming a galactic threat. Semhess attempted to use RS-33 enhanced subjects to stop the invaders, but during their fight with Marlon Fenn the station's containment systems were damaged and RAK-5 serum started leaking into atmosphere. It soon turned both RS-33 test subjects and personnel such as Icarr Ko and Nyris Ko into Rakghouls. When the Alliance strike team reached Alirra Semhess herself, she blamed the contanimation on them and tried to fight them off, but succumbed to the infection and turned into rakghoul herself. After killing her new form, the Eternal Alliance secured the station's containment systems and put an end to the project.
