Ramdha was renowned as the foremost expert on ancient Romulan myths, and had authored several books on the subject. She once appeared on the talk show Yrrh Mnrrh, where she spoke about Ganmadan. Secretly, she was also a member of the Zhat Vash. In 2385, she submitted herself for Admonishment and lost her mind in the process.
Ramdha was a passenger on the Imperial scout ship Shaenor when it was assimilated by a Borg cube. The force of Ramdha's despair caused the cube to undergo a submatrix collapse that severed it from the Collective. Like the other Romulan xBs, she was left disordered after being recovered from the Collective. (PIC: "The End is the Beginning", "Absolute Candor", "Broken Pieces")
In 2399 at the Romulan Reclamation Site, Soji Asha received permission from Hugh to interview Ramdha. Asha wished to consult Ramdha in creating a shared mythical framework as a therapeutic tool for the xBs. During their conversation, Ramdha arranged pixmit cards, the last of which depicted Seb-Cheneb and her sister. Ramdha became hysterical and grabbed a sidearm from a nearby guard; calling Asha Seb-Cheneb and the Destroyer, she pointed the disruptor at Asha before turning it on herself. Moving with inhuman speed, Asha disarmed her before she could fire. (PIC: "The End is the Beginning")
Later, Narek found Asha watching over Ramdha's unconscious body. He remarked that Ramdha had always been a "tormented soul", and that he was not surprised she had attempted suicide. Asha admitted that she felt drawn to Ramdha, that Ramdha had perceived something within her. (PIC: "Absolute Candor")
Before Narissa departed the Artifact to join an attack on Coppelius, she visited Ramdha and talked of their past. She noted that Doctor Kabath had not found any medical reason for why Ramdha had not regained consciousness. (PIC: "Broken Pieces")
