You follow the man to an area of the perimeter wall that encircles the tower. There, a body lies in the snow.
"We stumbled upon him when we were patrolling the wall," says the warrior. "Had to clear the snow away to get a good look. A single man, alone in the wilderness, yet he looks only recently dead." He scratches at his beard thoughtfully. "What do you make of it?"
The dead man is wearing dark robes like those of the ascetic religious orders that exist far to the east. A hood that would once have covered his head is thrown back to reveal a partially caved-in skull, the blood frozen among matted hair. Pinned to the man's robes is a metal brooch consisting of four lines that cross in the center, surrounded by a circle to form an eight-spoked wheel.
