An Advanced Creature Profile by Vincent Groth. 

The Duine le Masc are of the Sidhe Duine. Are Androgynous creatures with no bodyfat, large eyes that sit on the side of their faces giving them better peripheral vision, and needle-like teeth. They have pale grey skin, sparse white hair, and large hands with retractable claws. They dwell in dark places and dislike the touch of light.  

The Duine Le Masc are dangerous, deceitful creatures and masters of Glamor shaping unmatched beauty in forms to invoke obsession and wanton lust. They can use their glamour for far more than giving inhumanly beautiful appearances but can also create glamours that mimic the sensation of wind, the touch of warm flesh, and rain making them some of the most naturally gifted wielders of Glamour. Their Glamour is powerful enough to manifest into reality with enough time and focus. 

The Duine Le Masc feed off creativity, inspiration, and vision preying on artists and keepign them as pets in their nearly eternal halls. The Duine le Masc are the leaders of the Sidhe Duine and keep their kin in line beneath their iron wills. 

The Duine Le Masc like most Sidhe Duine are ageless creatures vulnerable only to physical force. Iron kills their magic wounds from iron rob them of their Glamour; the bite of silver is toxic to their bodies crippling them with unending agony. Only lethal blows from silver and iron together can kill them. Rowan and Hawthorne Stakes can place them in endless sleep until one or both are removed. The Duine Le Masc cling to darkness as their perfect glamour forms appear a little uncanny in direct light. They can be caught in natural circles of mushrooms or trees.
