Sylcine
Robed in a pure white toga, Sylcine, Maiden of Regret was once a devout servant to the Malevolent One, who resided at the pinnacle of the Baelgrim Fortress. Fond of shrunken heads and other severed appendages, her beauty was only marred by the random-body parts-turned jewellery that she wore in shamanistic fashion.
In the Year 641 AF an insurrectionist faction of daemons sent a number of scouts to test Baelgrim's defenses. They kidnapped Sylcine, and severed one of her fingers to be sent as a warning to the citizens of Mhaldor. A battle party was quickly assembled, lead by Taraza and with assistance they managed to enter the Inferno proper where they fought the daemonic legion and rescued Sylcine.
It was discovered in the Year 763 AF that as some point after her kidnapping, a servant of Lord Twilight by the name of Dusk, the Listener, had assumed the guise of Sylcine and infiltrated Mhaldor. With the assistance of Lyrudo, the Emael'daon Razor, Dusk was slain revealing to the world his century spent as an imposter.
The current fate, and or whereabouts of Sylcine are unknown, but it is overwhelmingly likely she met her demise shortly after being kidnapped.
