Finn came of age knowing nothing of the world that once was.
Cthulhu was released prior to his birth, and madness has since loomed over humanity.
Although Cthulhu never left R'lyeh, his call continues to lure victims by the boatload.
On every continent, societies prepare their young against Cthulhu's telepathic reach. Teaching them to resist the allure of R'lyeh, lest they be swayed to their doom.
Bad dreams and monsters under the bed are no longer scoffed at, they are active threats to humanity's survival.
No one is exempt, no location is beyond reach, not even the depths of one's mind are off-limits.
The frailty of humankind has never been on grander display.
