Birthed by Atlach-Nacha in the dark cavities of Cykranosh, the myriad hatchlings dwell in the space between, appearing only to prey on the dreamers that become caught in their mother's ever-expanding web.
At the end of the Mythos Phase, an investigator with the Crux of Cykranosh Artifact may lure the Spider-mother's brook into the open; spawn The Brood Epic Monster on his space.
At the end of the Mythos Phase, if The Brook Epic Monster has been defeated, solve this Mystery.
