Deltic, nicknamed Lieutenant Strangechild by her crewmate Commander Nibiru Chamas, was a human lieutenant in the Imperial Navy and the planetary science specialist of the Imperial Star Destroyer Ultimatum during its mission to the Gorse system in 11 BBY. She provided a report for the industrialist Count Denetrius Vidian and Captain Rae Sloane on the possibility of destroying the moon Cynda using explosives, causing Vidian to set in motion such a plan to more efficiently harvest the mineral thorilide.
