Known to most as vampires, the Thuul are vulnerable as nothing so much as they are to light, and, in particular, the unspeakable cosmic radiance of a multi-world-apocalypse.
So when the end came to their planet of shadow, the Thuul scattered like insects as they fled into the tunnels that dotted the landscape like so many trypophobic nightmares.
The creatures who remained on the surface–cattle, blood-beasts, wolves–were obliterated by that line of light in the sky. But the Thuul would persist for some time yet.
For the Thuul are everywhere, and have been everywhere for all time and this apocalypse was one of many that the brood of Lilith had survived. For beneath the surface of their planet was a vast subterranean network filled with computers and machinery and portals to other worlds sealed behind heavy metal doors.
Thuul, Upir, Vampire. In many worlds they were known and into many worlds did they flee. Every escaped vampire, however, found themselves in other worlds where the end was similarly taking place, such that there was no escape, anywhere from that blazing line of light.
Explanation:
I’m forcing myself to keep this one brief, because the Thuul are probably one of my best-developed ideas and it would be easy to get carried away. So…
I enjoy looking at the “logical conclusions” of unlikely events. In regards to vampires (my most favourite monsters) it seemed, well, logical to me that they would have reached an advanced stage of civilisation.
My vampires then, my Thuul, are perhaps the most technologically advanced faction to exist in my fiction. Using upcycled Soviet-era machinery, kabalian steampunk schematics and a literal eternity of experiment and experience the Thuul have spread their influence throught every world in the multiverse.
Their goal is to bring about the reunification of the Dark Sun, which would plunge all worlds into the Great Dark (that’d be Satan) and end the Arrogance of Autolycus (that’d be the eternal war between Love and Strife that rages across all realms).
Anyway, they get their just desserts here, I suppose.
Trivia:
The Thuul are heavily inspired by Brian Lumley’s Whamphyri.
