Copperwaifs were a rare variety of waif found in the Nightwoods. Like all waifs, they possessed the ability to communicate silently via telepathy. They had copper-coloured skin and, like greywaifs and ghostwaifs, had four long, ringed barbels protruding from around their mouths. The city of Riverrise was founded by Golderayce One-Eye, a copperwaif. During the Third Age of Flight, some copperwaifs settled at Riverrise, but some remained wild, attacking unwary travellers on the Waif Trail.
