Ghost is a heavy metal band formed in Sweden in 2006 well known for its theatrical performances which include pseudonymous personas, extensive costumes, and mimicry of traditional Roman Catholic imagery. For over a decade, the identities of the band members were unknown, but in 2017, the lead singer known as "Papa Emeritus" was revealed to be Tobias Forge. The other band member, referred to as "Nameless Ghouls", are not permitted to disclose their involvement with the band . However, Ghost has a large fandom which has deduced the real identities of multiple members. On early tours, the number of Ghouls was limited to five, each identified as either the element of Fire, Aether, Water, Air, or Earth. But the "A Pale Tour Named Death" (2018 - 2020) saw their number increase to seven while the Imperator (2022 - 2023) and Skeletour (2025) included eight.
