Iä! Iä! CthulWho Fhtagn! 

In a hidden base in the frozen northern borderlands, researchers from the ultra-secret Office for Research of Unusual Science (ORUS) poke, prod, and probe a handful of hapless Mythos monsters. These horrific creatures, imprisoned in the bowels of a repurposed military bunker, await an opportunity to escape their anthropoid captors. 

Meanwhile, CthulWho, the Great Lord of Space and Time, seethes on a nearby islet, his nefarious travels interrupted by a magnetic surge that damaged his reality-bending Radio’Luminescent Yonder-Epoch Habitationizer (R’LYEH). And, while the imprisoned monsters lie sleeping, dread CthulWho visits their dreams and calls on them to help him escape this dismal reality. 

It is up your players, whether acting as Deep One, Ghoul, Elder Thing, Shoggoth, or Mi-Go, to escape from their cells, explore the complex they are in and overcome its defenses — and answer the Call of CthulWho! 

This complete, self-standing, offbeat Mythos horror scenario uses the bestselling rules-light TSRPG (Travel-Sized RPG) narrative game system; is fully illustrated by artist Bob Greyvenstein; and includes everything needed to play it, requiring no additional resources.
