Sentis
Lady Sentis was the sister of Rubus. A vampire, she was the leader of the Cult of Acantha in the 819th Universe.
Like other members of the Cult, she wore dark robes with a high collar, and could use the Shadow Pathways to travel across the Multiverse. She also had the ability to turn into a creature of shadow herself (as well as the more traditional bat), and she possessed a red amulet which gave her some telekinetic abilities. Although proud and unyielding, she was less impulsive and more practical than Rubus.
The two travelled to the Interdimensional Black Market on behalf of the Echo herself to steal Acantha's robes from the auction and hire the services of Lainya Vantrik. However, the plan went wrong when Vantrik refused to carry out the task for which she'd been hired (as Rubus and Sentis has overlooked her rule against taking contracts on children and teenagers). In her anger, Vantrik even tried to kill Rubus, though he was saved by Sentis, who grabbed him and evacuated him through the Shadow Pathways. After the dust had cleared, Rubus and Sentis agreed that all was not lost, and agreed to try and capture Briar to extract the spirit of Acantha from her. (PROSE: Century Smith and the Time Terror)
