Servants of Yuggoth

 It is truth to say the Heirophants of Atlantis are immortal, but that longevity comes with a terrible price. The masters of Atlantis serve the Mi Go, who are sometimes called the fungi from Yuggoth. The surgical skill of the Mi Go enables them to extract the brain and preserve it alive in certain nourishing formulae. Then the bodies are prepared much in the same manner as one would prepare a mummy, drying the flesh until it becomes of a leathern quality. The Fungi then add certain apparatus into the spine of the lich,  that the disembodied brain may have perception and control of the body, much in the fashion of a puppeteer manipulating a wooden doll. The bodies are dependent upon the Mi Go to maintain the apparatus of control, thus do the Mi Go truly rule Atlantis. A mage of sufficient ability need not fear the Atlanteans, for the process renders them deprived of the means to properly conduct the subtle etheric energies, making their thaumaturgy mediocre at best. However the Mi Go are to avoided at all costs as they possess magic and knowledge inconceivable to the human mind.

   The Prophets of Pnom have often spoken of the doom that will befall Atlantis and of the pathetic bottled brains who will spend untold millenia buried on the ocean floor after this cataclysm. They will dwell trapped within their thoughts until the final death plunge of the Earth into the Sun grants them oblivion.

Spawn of Cthulhu

Cthulhu Talisman on display at Miskatonic University

   I asked the old shaman if he could call forth the god he claimed dwelt beneath the sea, his reply was that his god, Cthulhu was dead, but still dreamed and spoke to men in dreams. Great Cthulhu could not live again until the stars were right, but the shaman could call to the sons of Cthulhu as proof of the reality of his religion.
  I scoffed as any educated man would, daring him to follow through on his boast. The old shaman hobbled down to the water's edge, he traced a few cryptic symbols into the sand then began to chant a formula written on a tattered scroll. The chant grew into wild shrieking, "IA IA CTHULHU, N'YOG UN CTHULHU", as the old man waved about with a curiously carven little amulet.
  My mockery turned to stark terror as the water began to boil and a thing stright out of nightmare broke the surface. The head that rose was like an octopus but larger than an elephant's, the eyes shone with ancient inhuman intelligence and fixed me with their gaze. I stood paralyzed as the thing dragged itself onto the beach with wiry arms ending in taloned hands large enough to crush an ox. The thing had stubby leathern wings folded to its back and a long sinuous tale that began to transform into legs as soon as it cleared the water.
  I would have died there but for my trusted servant Giles. He rushed forward with a machete, hacking at the creature's newly formed legs. The beast snatched him up with blinding speed, Giles screamed briefly before the monster tore him in half. In that instant the thing's hypnotic gaze was turned from me and I fled into the jungle.
  I ran until I thought my heart would burst from the strain, not stopping until I made the ship. I held my sanity long enough to order the captain to sail and then collapsed into a gibbering heap, crying out for mercy from the Spawn of Cthulhu.

Fungi from Yuggoth

For thousands of years the Fungi from Yuggoth have visited Earth, mining rare minerals and performing ghastly experiments on mankind. Early in man's history a group of deranged individuals began to assist the Mi-Go in their projects, serving them in hopes of gaining immortality as disembodied brains. The aliens left their servants tools and instructions to carry on their gruesome work. This harvesting of human tissue continues even now, often labeled as the work of serial killers or under the veil of war crimes. But a few learned men understand the true nature of such atrocities and the Mi-Go move ever closer to their ultimate goal.

Intercepted transmission; MAG-12 LEVEL CLEARANCE ONLY:
 Subject: Adam Sexton age 26
 Suspected Mi-Go operative involved in harvesting operations.
 09/17/04 Sexton was shot 11 times and terminated by local law enforcement agents during an attempt to serve a search warrant at his Kentucky residence. Deep cover MAG-12 agents involved recovered Sexton's surgical instruments and various ancient texts from the scene, artifacts considered to be of yuggothian origin. Sexton's body was autopsied on site, abnormal fibrous tissue was discovered connecting the brain, spinal cord, and disfigured vital organs. Samples were collected and are in route to "51", critical details of incident successfully repressed from media.
 09/18/04 UPDATE:
 Sexton corpse missing,  Agent "David" killed, along with several locals. We are conducting a sweep of the area and expect....
 Transmission terminated abruptly.
 11/23/04 UPDATE:
 Subject Sexton spotted in Seattle, several incidents of "brain surgery murders" reported in that area. Sexton is considered a red level threat and is to be liquidated on sight. Recommend immediate cremation of subject.

Migo Artifact recovered, likely to be some sort of "scalpel" device used in the harvesting of brain tissue by Mi-Go operative. Artifact displays no obvious function and appears to be inert, in keeping with other yuggothian technology it may require a biological power source supplied by the user, this process allows the Mi-go to be fully integrated to their tools and explains the variety in their appearance. The alien devices can integrate with human tissue and function with varying degrees of success but the process is both physically and mentally detrimental to humans.
