One Mother of Faction Paradox had a mask carved from the skull of one of the Ferutu. Her shadow-weapon was a simple knife, but she seemed to be able to use it to sever individuals from Time.
She travelled to Gulliver's Rest some time after the Battle of Golgalith in the company of a Father, to try and get Dionus to sign over control of an as-yet-unformed temporal anomaly to the Faction, in exchange for their helping out with the running of his clinic. Dionus rejected their offer, prompting the two to erase his wife Susit from time in retaliation.
The same Mother was later one of the Skulltroopers sent to Gulliver's Rest by the Faction in a military context when the Enemy, the Great Houses' Fifth Time Fleet and the Faction began actually fighting over the planet. She briefly met Dionus again, taunting him with the knowledge that all could have been different if he had taken the Faction's offer, and also ook his child Egar from him. She was then shot from behind by a House Military soldier, her whole body crumpling to ash in a flash of energy, leaving only her mask. (AUDIO: Eternal Escape)
