Tindalos Hound, a bizarre entity originating from a dimension space of lines and angles only.
Although called "hound," its external form bears no resemblance to any canine. It is essentially a constantly flowing, twisted viscous Black Shadow, covered with numerous ominous red glowing eyes and cold gleaming Sharp Tusks.
They relentlessly pursue Prey without rest, hence the name hound.
Any angle less than 120 degrees, whether a doorframe's right angle, a tabletop corner, or even a smaller spatial angle.
Could become the doorway for them to infiltrate the real universe. When a space angle tears a logical-defying gap, and dense ink-like black fog spreads out, it is a sign of a Tindalos Hound's arrival.
They are nearly Immortal beings, like reflections in water. You can punch through the water basin, but how can you truly shatter the moon's reflection in the water? Even if temporarily repelled or destroyed, they can return at some future obscure "angle."
