Robert E. Howard,
The People of the Black Circle
“ There on the ledge stood four men. It was miraculous, incredible, impossible, yet it was true. They were not ghosts or phantoms. They were four tall men, with shaven, vulture-like heads, and black robes that hid their feet. Their hands were concealed by their wide sleeves. They stood in silence, their naked heads nodding slightly in unison. They were facing Khemsa, but behind them Conan felt his own blood turning to ice in his veins. Rising, he backed stealthily away, until he could feel the stallion's shoulder trembling against his back, and the Devi crept into the shelter of his arm. ”
