Doppelgangers, otherwise known by themselves as Shallar, were monstrous humanoids, infamous for their shapeshifting abilities that allowed them to mimic almost any humanoid creature. There was also a stronger, more capable subspecies known as greater doppelgangers or mirrorkin.
"I've been so many people I can hardly remember my own name... Sometimes I wake up and have to touch my face to remember who I am that day. And sometimes I can't remember whether I'm supposed to woo you or kill you without glancing in the mirror first."
-- Aunn, doppelganger spy
Description
In their true form, doppelgangers appeared as tall, elven, gray-skinned humanoids, whose thin hairless bodies made them appear, to human eyes, sexless. Their heads were bulbous, with formless faces and bulging eyes that were a pale yellow hue and lacked visible pupils. Though even this form was deceptive, as it gave the impression they were physically weak, when in fact they were quite strong and agile.
Personality
They were lazy but cunning creatures, who killed or disposed of people then assumed their place. While not actually evil, doppelgangers were extremely self-centered and liable to look down on their victims.[6] Because of their laziness and selfishness, they rarely ever had any interest in raising their young.
