The Cult of Dumazu is an ancient pre-American society of primitive fanatics and sorcerers that once worshiped the demonic deity Dumazu and antagonists in the 2011 video game Ghostbusters: Sanctum of Slime.
For centuries, the Cult of Dumazu who began within the New World (Americas), numbered in the hundreds and they worshiped Dumazu the Destroyer, mostly out of fear than respect. Each member of this cultic tribe wears a monk-like robe that obscures their identities. They practiced obscure forms of magic and funerary ceremonies. They also even once praised the mystical power of the object called the "Relic of Nilhe" which is quite useful for their lord Dumazu, though it is unclear whether they created the relic or not.
In 2010 B.C., they gathered at the Temple of the Destroyer for the funeral of their god. They chanted his name in his honor but at the same time, they feared death could only imprison Dumazu for so long. This was the last time anyone had seen or heard the existence of Cult of Dumazu.
Fast forwarding to present day... The last surviving member of this cult was Ismael McEnthol and in the modern time, he succeeded in temporarily reviving Dumazu before the junior team of the Ghostbusters defeated him, thus ending the Cult of Dumazu once and for all.
- The Cult of Dumazu share certain similarities with the Cult of Gozer, also due to the fact their immortal masters Dumazu and Gozer share the same titles which are "The Destroyer" and "The Destructor".
