Location: Beyond normal space time
Threat Assessment: 6. Though called "hounds" they are no relation to canines. They are creatures from another space time and can travel through time and enter our world through any sharp angle. They will hunt down anyone that catches their interest without fail, even using other entities to aid them.
Limitations: They need a corner to emerge from. rounded corners will stymie them for a bit.
Personal Note: It is never revealed if "Tindalos" is a place or a person.
