A Kelpien scientist aboard the research ship KSF Khi'eth, stranded in the Verubin Nebula, whose recorded distress call leads Discovery to her son Su'Kal and to the source of the Burn.
Doctor Issa appears in recordings and as a hologram in the third season of Star Trek: Discovery, played by Hannah Cheesman. Her ship went into the Verubin Nebula in search of dilithium and crashed on a planet rich in it. She was pregnant at the time.
Her distress message, still repeating more than a century later, is decoded by the crew, and Saru is deeply moved by the sight of another Kelpien. In Su'Kal he and the others reach the wreck and find the elaborate holographic nursery she built to raise and protect her child.
In That Hope Is You, Part 2 a recording shows her death. The young Su'Kal's cry of grief, amplified by the planet's dilithium, is what caused the Burn.
