Eclipse Cthulhu: Bestiary

Making Mythos Monsters Menacing
The average Eclipse Phase character carries enough weaponry to
trivialize many of these creatures if simply thrown into a fair
fight with them as they are statted here. However, every
intelligent race in the cosmos is smart enough to avoid a fair
fight, and likewise knows better than to come unarmed. The
intelligent species presented here are thousands of years more
advanced than humanity, and will undoubtedly employ
technology far beyond transhuman capabilities to give them an
edge. Their devices might bend gravity, magnetic fields, or even
time itself, or perhaps they could emit waves which interfere
with transhuman thought, affecting both biological and
cyberbrains. The Exsurgent Psi Epsilon sleights in the corebook
are a good start, but remember that the average Epsilon capable
exsurgent is a monster barely hanging on to sanity, while the
races of the mythos have had centuries if not millennia of
calculating study to perfect their craft.
It goes without saying that the more technologically advanced
extraterrestrials are more than capable of replicating the effects
of almost any transhuman hardware, from augmentations to
weaponry. Spotting something like a Deep One or Tcho Tcho
probably won’t cause any psychological damage, while a
Shoggoth or Star Spawn will pile on the mental stress.
New Trait: Not of This Earth
Beings which are Not of This Earth have alien biology, perhaps
being composed of exotic elements or matter not found on earth.
As such they are immune to electric shocks, toxins, and
biological agents.

Deep Ones are a sentient race of amphibious race of marine
dwelling bipeds. The species originated on earth, and while
certain anthropologists argue they share a common ancestor with
humanity, it is certain that the Deep One race far predates
anatomically modern man. Deep Ones make their homes far
below the surface of the ocean, dwelling in breathtaking
underwater cities. They worship Cthulhu along with Dagon and
Hydra, two enormous Deep Ones said to be the eldest of their
race, although all Deep Ones are immortal. Deep Ones are
rarely seen on land, emerging only occasionally to mate with
groups of humans whom they have formed special pacts with.
The offspring of these pairings appears human at first, but as it
ages its amphibious traits begin to express, eventually
transforming the hybrid into a full Deep One.

"Objects are eight feet long all over. Six-foot five-ridged barrel
torso 3.5 feet central diameter, 1 foot end diameters. Dark grey,
flexible, and infinitely tough. Seven-foot membraneous wings of
same colour, found folded, spread out of furrows between ridges.
Wing framework tubular or glandular, of lighter grey, with
orifices at wing tips. Spread wings have serrated edge. Around
equator, one at central apex of each of the five vertical, stave-

tentacles found tightly folded to torso but expansible to
maximum length of over 3 feet. Like arms of primitive crinoid.
Single stalks 3 inches diameter branch after 6 inches into five
sub-stalks, each of which branches after 8 inches into five small,
tapering tentacles or tendrils, giving each stalk a total of 25
tentacles.
At top of torso blunt bulbous neck of lighter grey with gill-like

years old. From inner angles of starfish-arrangement project
two-foot reddish tubes tapering from 3 inches diameter at base to

leathery, but extremely flexible. Four-foot arms with paddles
undoubtedly used for locomotion of some sort, marine or
otherwise. When moved, display suggestions of exaggerated
muscularity. As found, all these projections tightly folded over

Elder Things are an advanced alien race of great wisdom and
power that visited Earth in bygone prehistoric ages. The vast
majority of Transhumanity’s knowledge of the species comes
from long fossilized paleontological specimens and a few
sandblasted ruins on mars, but all available evidence points to
the existence of a vast interstellar civilization, possibly still
extant elsewhere in the galaxy. According to some researchers
on the absolute fringe of scientific credibility, much of Earthly
life bears the mark of these barrel shaped crinoids’ genetic
experimentation. Elder Things are able to physically traverse
space by unknown means, with xenobiologists’ hypothesis
ranging from their wings functioning as solar sails, to the “head”
serving as a miniature ramscoop, gathering loose hydrogen
atoms for use in a biological jet engine.

K’n-yan
“To see that the mutual encroachments of pleasure-seeking never
crippled the mass life of the community—this was all that was
desired. Family organisation had long ago perished, and the
civil and social distinction of the sexes had disappeared. Daily
life was organised in ceremonial patterns; with games,
intoxication, torture of slaves, day-dreaming, gastronomic and
emotional orgies, religious exercises, exotic experiments, artistic
and philosophical discussions, and the like, as the principal
occupations.”
K’n-yan are immortal, telepathic, sadistic hedonists who
populate a vast underground civilization beneath Northern
Mexico. Their civilization long ago achieved complete physical
mastery over their own bodies, granting them both immortality
and the power to de and rematerialize at will. Their scientific
achievements were also staggering, by the time the human
industrial revolution was beginning on the surface, the K’n-yan
had already abandoned the vast majority of their technological
developments out of sheer ennui, keeping only what was
absolutely necessary to fulfill their personal whims. To this end,
they employed their skills in bioscience to develop servitors from
several slave races to autonomously perform all manual labor
necessary to sustain their standard of living. This left the
terminally bored K’n-yan free to descend even farther into
religious fervor and mindless hedonism, constantly seeking new
sensations to combat the tedium brought on by centuries of life.
The K’n-yan chiefly worship Yig and Cthulhu, who they know
as Tulu, although some also venerate Shub Niggurath and her
children Nug and Yeb. The K’n-yan originally sealed their
underground civilization from the outside world when R’lyeh
sank beneath the waves, long before the advent of modern man.

K’n-yan, if sleeved in their original bodies, are capable of de and
rematerialization of both themselves and, to a lesser extent, other
objects around them. This ability allows them to pass through
any “solid” object. Furthermore, this ability permits them to
avoid all non-area attacks directed at them entirely if they are
able to pass a Ref*3 check. K’n-yan may dematerialize small
objects, or unwilling targets by winning an opposed Will*3
check. These objects rematerialize if the K’n-yan’s
concentration is broken.
All K’n-yan are telepathic and, regardless of the body they are
sleeved in, are assumed to possess any Psi-Gamma and Chi
sleights they desire.
Mi-Go
“They were pinkish things about five feet long; with crustaceous
bodies bearing vast pairs of dorsal fins or membranous wings
and several sets of articulated limbs, and with a sort of
convoluted ellipsoid, covered with multitudes of very short
antennae, where a head would ordinarily be.”
The Mi-Go, or “Fungi From Yuggoth,” are a sentient race of
extraterrestrials, resembling malformed, winged crustaceans.
The Mi-Go are able to travel through interstellar space without
technological assistance by unknown means, and in the archaean
past arrived in the Solar System to alight on Yuggoth. They are

Shoggoths have a Som value equal to their current Durability.
They do not suffer Wounds, and cannot be harmed by Kinetic

is roughly the size of a basketball. At any size, a Shoggoth can

Shoggoths which successfully grapple a target with a

movement, may envelop the victim. Enveloped victims take
