Shaggai, also known as "Chag-Hai", is a planet that orbits around a binary system with green suns. Thick inhabited jungles and dark seas grew on their lands. It was the home of insects called Shans, as well as a mysterious being known as "The Worm that Gnaws in the Night". According to The Dweller of Darkness, he is found in the depths of the cosmos, even more than Yuggoth. However, it could somehow be reached by beings from other worlds, as related in the Book of Eibon by Eibon himself.
Appearance
Shaggai's landscape was terrifying: plasma-formed black sea, crystal-covered deserts, crystal-clear purple mountains, and forests with dense vegetation.
Actual state
Its current existence is in doubt, as the insects from Shaggai had to flee from Shaggai due to an attack on a planetary scale. Apparently, it was the Outer God Ghroth who brought destruction to Shaggai. In the evacuation, the insects used temples in whose construction an indestructible gray material was used, jumping from planet to planet until they reached Earth.
