There flapped rhythmically a horde of tame, trained, hybrid winged things… not altogether crows, nor moles, nor buzzards, nor ants, nor decomposed human beings, but something I cannot and must not recall. -H.P. Lovecraft, “The Festival.”
This interstellar race often serves Hastur the Unnamable. Composed of conventional matter, they are vulnerable to ordinary weapons such as pistols. Byakhee cna fly through space and carry a rider each, though such riders need protection from the vacuum and cold by suitable spells or potions. Byakhee do not have bases on Earth, but maybe summoned to preform deeds or to serve as steeds.
In combat, a byakhee may either strike with both claws simultaneously (getting two attacks in the round), or attempt to bite the target. If the bite strikes home the byakhee remains attached to the victim and begins to brain his or her blood. Each round the byakhee remains attached, including the first, the blood drains subtracts 1D6 hit points of STR from the victim until death. The byakee characteristically remains attacked with the bite attack until slain or the victim is drained of blood.
Escaping death, let the victim rest and regain blood by transfusion as well, at up to 1D3 STR per day.
