On stardate 2378.1 Raeger was part of a landing party to the Pharos siteworld in the Marrat Nebula, investigating the loss of contact with the engineers at Project Pharos. The Pharos site had been attacked by the IKS Varchas, and shortly after transporting down the landing party came under the attack by Klingons in the facility. Raeger was the first casualty, taking a disruptor hit to the back. (EV comic: "The Fires of Pharos")
- It is unclear whether or not Raeger survived his disruptor hit.
