Codex Vermithrall

As illustrated in the Shadowhunter's Codex.[1]

Vermithrall is a worm demon that collects into colonies and forms a humanoid, lumbering, monstrous mass of thousands of writhing worms which attack as a unified single entity. When separated from the colony, it will endeavor to rejoin the main body, making the Vermithrall a difficult demon to dispatch and kill permanently.[1]
