Hound of Tindalos (on left): The Hound does not receive its name because of its appearance, as it lacks any stable anatomical features. Instead, it funnels energy from its own dimension and emerges through an angle to “evolve” a temporary body that allows it to “hound” its prey.
Hunting Horror (on right): As described, this is not a single organism but a tendril that connects to a larger, transdimensional being. Because of this, every Horror is slightly different (just like our neurons have different shapes depending on their function).
