Feeding the Byakhees

"Slowly, the monk continued peeling. With precise gestures, he teared the flesh from the exsanguined head, revealing the skull underneath. Here and then, he throws high in the air a bit of flesh to the strange birds in the sky, which in turns plunged with astonishing speed to catch the horrible treats.

That's when we noticed it was no bird. No !

...Byakhee... slowly said Garth the ghoul."
