Pr'H'Ska was a female Horta member of a joint Human/Horta mining crew stationed on Lythos Prime, colloquially known as Rockpile. She was described as reliable, loyal, and emotionally steady. She served as the Chief Horta Engineer and implemented a voice modulator and mechanical arm to interact with her human colleagues.
When a Borg cube appeared over Rockpile in search of a carbon-silicon hybrid, Pr'H'Ska recounted tales of the Borg she heard from her mother when she was young. After proclaiming that Horta are peaceful and abhor killing, she and fellow Chief Engineer Nellis tricked the Borg until they decided assimilating Horta was not worth their energy and departed.
