A male human doctor by the name of Mullmoy practiced medicine on the planet of Ferrix throughout the Imperial Era. In the year 5 BBY, Mullmoy went to the Andor household in order to examine Maarva Carassi Andor, whose health was deteriorating. Jezzi, a member of the Daughter of Ferrix, informed Mullmoy as he neared the house that Maarva was refusing to take the medication that Mullmoy had prescribed. Ultimately, Maarva passed away, and a funeral was organized in her honor. Mullmoy played a musical instrument while walking in the direction of Rix Road during her funeral.
Mullmoy, a doctor, appeared in two separate episodes of the show Andor. Matt Dunkley, the orchestra conductor for the series, played him in a cameo appearance.
