Dahh-Ren

Dahh-Ren worked for IRC Mining aboard the Starship Forge. His smartsuit was off-network when the remaining suits received a command to deactivate their living components. He was, therefore, one of the four survivors present when the Fourteenth Doctor arrived aboard the station. He was the only non-human survivor aboard the Starship Forge.

He disliked being called "Darren", and accused Erin Stevenson of being racist, in response to his blue skin.

He was eventually killed in the Forge's Section 12 when the smartsuits instructed his own suit to disable its organic component. (DW: Those Who Lead)
