Hounds of Tindalos

Hounds of Tindalos are extra-dimensional creatures capable of moving through space and time freely. They were created by Frank Belknap Long and later incorporated into the Cthulhu Mythos when it was codified by August Derleth. They first appeared in Long's short story "The Hounds of Tindalos", first published in 1929. Lovecraft mentions the creatures in his short story "The Whisperer in Darkness" (1931).
Appearance of Hounds is unknown, since neither Long nor Lovecraft describe them, arguing they are too foul to ever be described. In Long's original story, which deals with the main character experimenting in time travel with the help of psychedelic drugs and esoteric artifacts, the Hounds are said to inhabit the angles of time, while other beings (such as humankind and all common life) descend from curves. It is said that once a human becomes known to one of these creatures, a Hound of Tindalos will pursue the victim through anything to reach its quarry. A person risks attracting their attention by traveling through time. They can materialize through any corner if it is fairly sharp - 120° or less.
