The Worm that Gnaws in the Night is a fictional entity in the expanded Cthulhu Mythos. The character was originally created by Lin Carter for his short story "Shaggai".
Background[]
The Worm is a massive polychaete worm-like fiend that was observed by the wizard Eibon, who noticed that it was slowly eating away at the planet Shaggai.
The Worm has immense durability and might be one of the most powerful Great Old Ones. The Elder Gods couldn't even handle it and the Worm has survived the radiation from Ghroth, the Outer God who destroyed all life on Shaggai. It was one of the only Old Ones on that planet, with the other being Baoht Z'uqqa-Mogg.
