USS Dorian
From Star Trek: Theurgy Wiki
The USS Dorian was a 24th century Federation starship operated by Starfleet.
Ian Hawthorne served aboard the Dorian as an executive officer with the rank of lieutenant commander from 2634 until he was promoted to commander and transferred to the USS Terminus in 2370.
In 2370 the Dorian was attacked by mysterious entity that had gotten onboard. The entity was destroying the ship from the inside, forcing the Dorian’s commanding officer to give self-destructive orders through the use of torturous electric shocks. First Officer Hawthorne bravely stepped in, using his own body to absorb the shocks long enough for the captain to break free. Unfortunately the Dorian’s commanding officer died and Hawthorne lost his right hand, but the ship was saved and Starfleet awarded Hawthorne Starfleet Medal of Honour and provided him with new, prosthetic hand so he could continue serving.
(It is not been revealed what class of starship the USS Dorian was, but if its first officer was a lieutenant commander it is likely that it was a small to midsize 24th century vessel such as a Miranda or Oberth class.)
