|“||They're like dragons. They like to stockpile sparkly things. Junk, jewels, it's all the same to them.||”|
Vetis demons are dragon-like creatures that tend to hoard things that sparkle—whether they are valuable or not.
Vetis demons are said to somewhat resemble dragon demons. They are gray, scaly, and tall, having elongated but human-shaped bodies. They have long serpentine arms that end in eel-like heads. They have ruby-red eyes and a mouth full of pointed teeth that jut out in every direction.
In 1899, a group of senior students at the Shadowhunter Academy released a Vetis demon trapped in a Pyxis as a prank against part-demon Shadowhunter James Herondale. The demon killed Clive Cartwright, who had been holding the Pyxis when it was released. It was quickly vanquished by James and Matthew Fairchild.
