In 2558, Thomas Lasky and Spartan Naiya Ray accompanied Petra Janecek to Karava to meet Petra's contact, Zef 'Trahl, in Kor Delban. While visiting the city, Ray was challenged by a Sangheili, 'Lordan, and two others. However, the conflict ended when Janecek killed 'Lordan with her revolver, causing the other Sangheili to back off.
