  • Starflight A dark servant can survive in the void of outer space. It flies through space at incredible speeds. Exact travel times vary, but a trip within a single solar system normally takes months, while a trip between stars takes many years.


  • Multiattack. The dark servant makes two talon attacks (if flying), or two wing attacks and one bite attack.
  • Talon. Melee Weapon Attack: +10 to hit, reach 10 ft., one target. Hit: 2d8+6 piercing damage and the target is grappled (escape DC 18). If the dark servant hits the same target with both talon attacks, it gains a bonus action to use its rend attack.
  • Wing. Melee Weapon Attack: +10 to hit, reach 10 ft., one target. Hit: 2d6+6 bludgeoning damage.
  • Bite. Melee Weapon Attack: +10 to hit, reach 5 ft., one target. Hit: 2d6+6 piercing damage.
  • Rend. Melee Weapon Attack: +10 to hit, reach 10 ft., one grappled target. Hit: 4d8+6 slashing damage.


This huge, gaunt creature is roughly bipedal and batlike, with taloned feet and vast, membranous wings. Rank black fur, gleaming chiten, and putrescent ebon flesh covers its body.

Known in some circles as byakhee or star-steeds, the dark servants are creatures of the black spaces between the stars that can be summoned to the Earth through forbidden magic. They are native to the far-distant world of Carcosa, domain of Hastur the Unspeakable, and are most commonly encountered while serving as that terrible being’s minions or messengers to the Earth.

Dark servants also serve powerful cultists or magic-users as flying steeds.

Unlike many other extraterrenes, dark servants are rigidly bound by ancient pacts and serve their summoners obediently, provided the necessary rites are performed correctly. Even a small oversight can lead to catastrophe, because dark servants are very sensitive to their peculiar summoning rituals and always answer; they have been known to tear wizards limb from limb if some protective step is unfortunately omitted.

However, under the proper conditions, dark servants can be compelled to undertake tasks or obligations lasting for centuries-for example, appearing to bear away a summoner many years after being commanded to come when called, or returning to a specific place one day each year to perform a service for centuries uncounted. This makes them very useful as guardians or protectors of ancient secrets.
