Hounds of Tindalos



The Hounds of Tindalos are a hostile species of interdimensional dog-like creatures 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". HP Lovecraft mentions the creatures in his short story "The Whisperer in Darkness".

Overview
The Hounds are said to inhabit Tindalos, a dreadful dimension located at the angles of time, while other beings (such as humankind and all common life on Earth) descend from curves.

Though the Hounds are sometimes pictured as canine, probably because of the evocative name, their appearance is unclear, since neither Long nor Lovecraft describe them, arguing they are too foul to ever be described. It is said that they have long, hollow blue tongues or proboscises to drain victims' body-fluids, and that they excrete a strange blue pus or ichor. They can materialize through any corner if it is fairly sharp—120° or less. When a Hound is about to manifest, it materializes first as smoke pouring from the corner, and finally the head emerges followed by the body. It is said that once a human becomes known to one of these creatures, a Hound of Tindalos will target and pursue the victim through anything to reach its quarry. A person risks attracting their attention by travelling through time.

 * The Hounds are referenced twice in the anime Haiyore! Nyaruko-san. In one episode, Nyaruko offers to make Mahiro a hot dog using Hound of Tindalos meat; Mahiro angrily responds "Go bang your head on the angles of time!" In another episode, the corners of Hasuta's bedroom are shown to be covered with putty (presumably to proof his room against the Hounds).
