"A Mother's Hope," a brief narrative by Drew Karpyshyn, appeared in the developer's online journal for Star Wars: The Old Republic on November 17, 2016. This tale showcases Senya Tirall and her offspring, Vaylin, locked in a duel on the world of Ord Mantell following the Battle of Odessen, an event depicted in the Betrayed cinematic trailer.
Subsequent to the Battle of Odessen, Senya Tirall escapes with her gravely wounded son, Arcann, the former Emperor of Zakuul. Seeking sanctuary, she lands on Ord Mantell with the intention of connecting with a group of rebellious Knights of Zakuul who have declined to swear allegiance to the new Empress, Vaylin.
Senya discovers, upon her arrival, that the rogue Knights have been slain recently, and Vaylin is there, waiting for her. A heated confrontation ensues between them, but when a lightsaber pike, hurled by Vaylin, inflicts severe damage to the hyperdrive of a wrecked shuttle nearby, a significant blast occurs. The resulting explosion separates Senya and Vaylin, allowing Senya to escape and seek assistance in another location.
