"Terrible beings with a human-like stature flying through the air, cloaked by living shadows, appearing only at night," Maelon shuddered. "They bring the stench of death and decay with them. The red priests and warlocks could do nothing but delay the wraiths. Only the aeromancers, shadowbinders, and firemages from Asshai can vanquish them after much struggle. Valyrian steel also seems to harm them, but the shadow fiends are too hard to kill. They always attack in large groups; if you wound one, it will flee. We've lost hundreds of ships to these shadow devils in the last year alone!"
