Grach are four-lgged, winged, large and lumpy, with sharp teeth, large, sharp red talons, and flat yellow lizard eyes. They are scaly and leathery, with mottled green, yellow and grey skin. They have leathery spines growing on their backs, and three lashing spiked tails. Their bodies are covered in scales, although they feel both leathery and scaly. Grach's eyesight is poor, however they use their forked tongues to taste the air and track any scent. Their wings, used for flight, are large and leathery. Grace can grow large enough to hold six people on their backs, and strong enough to do it flying.
