The Glow-worm is a tiny, serpent-like dragon that lives in deep, dark caves and is very loyal to its owner.
These dragons are very small. They are described to look more like a worm than a dragon. They resemble the Arsenic Adderwing and glow in the dark.
Its bioluminescent spine glows in the dark and aids the dragon in hunting in dark caves. They are a useful source of light on moonless nights, or in caves. Vikings use them in lanterns to light up homes and ships in the night-time. They crawl on walls and sleep on ceilings.
They breathe a soft flame that glows more than burns.
The Glow-worm can also spew glowing sticky fluid from its nostrils to disorient its predators. It eats grubs and blind cave crickets that are found in or on Glowing Cave's.
