Sh'naal was a young Markab girl aboard Babylon 5 with her family at the time that the Drafa plague infected the population.
She was sent by her mother to look for her father whom was late for dinner, but when she found him he had already succumbed to the disease and was dead in the Zocalo. She was later taken into an isolation zone with the rest of the Markab population and guests Delenn and Lennier. She became separated from her mother when the two Minbari found her so Delenn stayed with her while Lennier went to go look for her. To aid in their search Delenn asked for her mother's name, the girl replied, "mama."[1]
