Investigation Summary

The fog clung to Millbrook like fingers of the dead, and with each passing hour, the investigators felt the weight of unseen eyes pressing down upon their souls. What had begun as a simple missing persons case was revealing itself to be something far more sinister.

Key Investigation Moments

  • The Library Discovery: Dr. Margaret Chen discovered the ancient tome hidden beneath loose floorboards in the Millbrook Public Library. The leather binding writhed beneath her touch as she opened to pages filled with diagrams that hurt to look at directly.
  • Blackwood's Revelation: Thomas Blackwood recognized the symbols from his years studying forbidden texts. His face went ashen as he whispered the name "Yog-Sothoth," and the temperature in the room dropped ten degrees in response.
  • The Basement Horror: Sarah Mitchell's police training failed her completely when they descended into the Wessex Farm basement. The walls pulsed with a sickly bioluminescence, and the missing townsfolk hung in cocoons that breathed with alien rhythm.
  • The Summoning Circle: The investigators discovered Ezra Wessex had been feeding the townsfolk to something that existed between dimensions. The summoning circle carved into the basement floor still thrummed with eldritch energy.
  • Sanity-Shattering Truth: Margaret realized the newspaper she worked for had been printing stories that were actually incantations. Every edition for the past month had been slowly preparing the town for harvest by entities that regarded humans as cattle.

Sanity Loss & Consequences

  • Dr. Chen: Lost 8 Sanity points, developed acute bibliophobia (fear of books)
  • Thomas: Lost 12 Sanity points, can no longer speak the names of Mythos entities without stuttering
  • Sarah: Lost 6 Sanity points, has nightmares about cocoons and will not enter basements alone
  • The town of Millbrook was evacuated, though official records list it as a "gas leak incident"
