Vhaeraun
Also known as The Masked Lord.
Son and enemy of Lolth. According to some legends, his mother scarred him for his arrogance, which is why he often appears masked. Stories also have it that his tongue had been cut out for daring to question his mother.
On an island of the Darklake, our heroes met Sakme Oblodra, a male Drow of the Bregan D'aerthe who was mute, masked, cloaked, heavily scarred and exceptionally strong. However, at this time they did not know of Vhaeraun, thus the significance was lost on them.
On the body of defeated drow was found a thin volume on heretical Dark Selderij gods, including Vhaeraun. In this book it was suggested that Vhaeraun wears a purple purple mask and a long cloak of the same color; it also mentions that other sources suggest it is black.
