In 1971, the wicked cult of science-sorceress Thelma O’Therion vanished from Oddfellows Observatory – and rumour is that the place has been growing ever since. Now, in the name of love, stoner-metal singer Terrance will discover the madness that lies within its walls – a terror transcending time, space, and sanity itself... Writing about ‘Supermassive Black Mass’, author Matthew R. Davis said: “The core idea had been kicking around in my head for a few years: what if a crew of astronauts returned after many years away to find the entire planet overgrown by a single haunted house? I couldn’t see my way in, so I reduced the SF element and decided on more contemporary characters. I didn’t know who they would be until I happened across a copy of Electric Wizard’s ‘Witchcult Today’ album, after which it seemed perfectly natural to make my lead a stoner metal frontman with a taste for ‘70s horror! I’ve extensive experience with all of those things, so writing [the character of] Terrance Cranston was no stretch at all – except that he’s had a fair amount of success, whilst I continue to toil in well-deserved obscurity.” (Short Sharp Shocks! Book 21.)
