The Mummy was one of many monsters captured by the Facility and was used to kill people to appease the Elder Gods. It is unknown what summoned it. The Mummy was seen during the Purge trying to grab a hysterical worker as he ran past it while trying to flee from the Dismemberment Goblins on their stolen golf cart. The Mummy was seen holding a curved dagger or knife, which it more than likely used to kill its victims. The Mummy was more than likely killed when the Elder Gods awoke.
