In 2535, she was ordered by the High Prophet of Regret to assist Thel 'Vadamee in his search for Kig-Yar who were making Covenant weaponry for humans, bringing along a pack of Jiralhanae under Chieftain Pellius. While scanning asteroids in the 23 Librae system, Chur'R-Mut brought her ship too close to Thel's due to her aggressive piloting, much to his annoyance. Thel believed that the Prophet of Regret sent her to keep an eye on him due to lack of trust.
When the two vessels discovered the Rubble, A Psalm Every Day fired on Thel's ship, Retribution's Thunder. Pellius then sent a mocking message to Thel, and Chur'R-Mut was no where to be seen, indicating that the Chieftain had overthrown her as well.
