Crewman Ishimura was a crewman on board the U.S.S. Defiant. She was a geologist.
- “Tenebris Torquent”: Ishimura is part of the Defiant's landing team on Havas-Kul, sent to establish a secure zone. She survived the initial attack by the Hur'q Mutant, but once she is found by the player she is grabbed from behind and dragged away screaming. Her lifesigns flatline shortly after.
- The fate of Ishimura and her fellow crewmen reflect the Star Trek redshirt trope. Their fates in being picked off one by one in a dark, hostile environment also mirror the fate of the engineering team in the DS9 episode Empok Nor.
- The name Ishimura could be a reference to ship of that name from Dead Space (video game), given the similar mortality rate of characters between Dead Space and Tenebris Torquent.
