The voice’s melodious quality was not dimmed by the silver mask that hid the foreigner’s face, and Alicia found herself listening intently to the stranger’s words. “Beauty like yours should, no, must not be allowed to fade.”
“All beauty fades m’lord.” she replied, wishing it weren’t true.
“If you come with me, I can make your beauty immortal”
“Would you have me painted?” She shifted into a more stiff position, her face glowing in the afternoon sun. “Or would you hire sculptors to make my likeness?” Her laugh rang like bells in the garden.
“No, I would make you immortal.”
Masque of Clavicus Vile
This silver mask was created to allow corporeal undead to walk amongst the living. It hides their appearance and smell, and even allows creatures who are harmed by sunlight to move safely during the day. It also dampens their supernatural abilities. Gaze and bite attacks are obviously blocked, and paralytic touches and energy drain attacks do not function while the mask is worn. The mask also confers an effective charisma of 14 on anyone who wears it.
