On moonless nights when ghouls run wild
and ghosties dance and scream and gloat
don’t fret, don’t cry, don’t fear, dear child-
Those ghoulies fear John Bloodycoat
Better stay away from him, he’ll rip your lungs out…
His hair was perfect…
I’d like to meet his tailor…
A secret MLM (pyramid) company that offers eternal life, but in fact it transfers the life forces of its members to those position "above". If you get high enough, (meaning you get enough new members) you start to enjoy the benefits. Maybe a willing sacrifice is much more effective for the transfer. But no one says, that a suddenly unwilling member, threatening to tell the authorities, may not loose it involuntarily... thus start people to vanish, and aged corpses are deposited somewhere safe.
