Sullen Plummet is the name of a female Slylandro who met with The Captain during the course of the Second War. When The Captain questioned the Slylandros about the Precursors, she remembers that the last time the Shaggy Ones visited Source, they came aboard a great circular starship. Whether this means she was actually present at this event or simply remembers that part of the history chants better is uncertain, but the information acquired from Slylandro Timekeeping suggests that the Slylandro lifespan is too short to permit her to see the Precursors face to face. She's rather shy, according to Content to Hover, who seemed to be attracted to her. When asked about her "glowy bits" (which are used for reproduction) by The Captain, she lost her ballast from sheer embarassment.
