Momaw Mowadan functioned as a doctor of the Ithorian species. He provided his services in the infirmary of the Kuari Princess ship. During the attack on the luxury liner by the Riders of the Maelstrom, Mowadan was present.
In Classic Adventures: Volume Five, when the Riders of the Maelstrom adventure was republished, the character's designation was altered to just "Doctor Mowadan," omitting his given name.
