The Peryton: Shadow Dimension Walker
Medieval monster hunters described a winged deer that cast a human shadow, born from the spirits of travelers who died far from home. The sci-fi Peryton exists simultaneously in our dimension and a shadow realm. Its body manipulates dark matter to phase between realities at will. That human shadow? Stored consciousness patterns from past victims, quantum-locked in extra-dimensional neural tissue. It hunts by shifting partially out of reality, becoming ghost-like when needed.
