Nightmare and Nocturne were a pair of tuk'ata (female and male, respectively) owned by Rin Sakaros, given to her by her brother Tariun and her sister-in-law Breek Zagrev after their wedding in 145 ABY. During the Battle of the Sith Star, Rin sent Nightmare and Nocturne to assist Jinyx Windrunner in battle after Tekk Draykhan was killed in battle. Both tuk'ata rallied some of Rin's Anzat hounds and massacred the Vyrak legionnaires attacking Kyriel, before racing off through the Sith Star in search of more enemies.
