Shaver Mystery Magazine (periodical)

The Shaver Mystery Magazine was an American periodical, sometimes described as a fanzine, dedicated to the Shaver Mystery, which details a global conspiracy involving the psychic harassment and abduction of human victims by a sinister group of underground-dwellers known as Deros, as well as an alternative history of the world involving the lost civilisation of Lemuria. The magazine was published by the Shaver Mystery Club (and Richard Sharpe Shaver) from 1947 through 1949, and notably featured artwork by the likes of Virgil Finlay, Malcom Smith, L. G. Jones, Harold McCauley, and others, in addition to stories and drawings by Shaver himself.

Mandark
The main story, serialised across each issue of the magazine, was Mandark, the Story of the Messiah as Told in the Caves, in which Shaver imagines "Yahveh" (as in Yahweh, Jehovah) as a black alien-god in the cavern world, who, among other things, becomes enthralled to a dero princess, being routinely and extensively tortured by her. The story also relates Yahveh's ongoing telepathic interactions with Jesus Christ, a process beginning when the child was still in his mother Mary's womb.
