Cthulhu Eternal: All Systems Mi-Go!

Things are ticking along nicely with plenty of folks picking up free (or donation-backed) copies of our first three SRDs for Cthulhu Eternal (Modern Age, Jazz Age, and Victorian Era). We’ve been delighted to see downloads of the SRDs recently click over to 1500 copies — and have been a little surprised to see that the Modern Day edition of the rules seems most popular with downloaders.

One comment we’ve received several times (for CE and also APOCTHULHU) is that it would be great if there were statted versions of Lovecrafts monstrous creations that could be easily dropped in to a Cthulhu Eternal scenario. Rest assured, on this particular subject we have something special planned.

Long-time readers of the blog might remember some discussion a couple of years back that scratched the surface on which of HPL’s creations are definitively in the public domain. This investigation was picked up by an amazing team of researchers in Germany who went back and re-read every public-domain Lovecraft story and created stats for the original monsters mentioned in their pages. They created their own (German-Language) RPG called FHTAGN which collected all these game stats into a fully-OGL sourcebook and free-to-access website.

The best part — the FHTAGN system is derived from the exact same game engine that we have used for APOCTHULHU and Cthulhu Eternal. So, their creature stats, ritual stats, tome stats, etc., are all fully compatible with our games. The only snag is that they are only available in German.

Recently, though, the FHTAGN folks — heartily encouraged by us — decided to translate all this treasure trove of fantastic material (some 40,000 words of game content) into English. As they do this, we will absorb (and maybe tweak if needed) their awesome material to be useful for APOCTHULHU GMs and Cthulhu Eternal GMs.

Mi-Go Don’t Love Me At All

So excited are we by the prospect of having fully OGL open creature stats for Lovecraft’s public domain creations, that we have jumped ahead slightly and had a few of the stat blocks from FHTAGN translated ourselves. So, without further ado, I bring you … the Mi-Go (or Fungi from Yuggoth)! More translated critters in coming days …


The Fungi from Yuggoth

The body of a Mi-Go is essentially comprised of a colony of fungal microorganisms. Each is part of a larger whole and together form an independent, functional unit that is designed for a specific task. Depending on the situation, a Mi-go’s physical form can be redesigned and reconfigured. As a result, eyewitness descriptions often differ, sometimes drastically. Some accounts describe encounters with hairy “snowman”, while others report cancerous beings. Still other people claim to have seen terrible fungal monstrosities. In fact, all are accurate reports.

In order to transport minerals and ores, Mi-go can form hair-like tentacles all over their bodies, capable of holding and carrying rocks. In combat situations, they can defend themselves with cancerous nippers.

In order to move unseen among communities of other beings, Mi-go have the ability to camouflage their exterior with a waxy substance. In this way, they can take on an almost human appearance. In some situations, Mi-Go may develop membranous wings that enable them to fly between planets (or even into the depths of interstellar space). The dense atmosphere on Earth makes these wings less effective, but the Mi-Go can still use them to (gracelessly) launch into flight and remain aloft for an extended period. One of their favorite tactics when engaging humans in combat is to grapple them up with their nippers (PIN maneuver) and drag their victim upwards into the sky – dropping them from a great height.

The “shell” that comprises the outer layer of a Mi-go’s physical form interacts with visible light in an unnatural way and therefore cannot be captured on conventional film or digitally. Because of this and because Mi-go have numerous sense organs that alien to human understanding, the creatures are extremely sensitive to light. During the day they retreat into mines and cave systems, usually only coming out at night.

STR 16   CON 14 DEX 13   INT 17 POW 15

HP 15    WP 15

Size category: Medium.

Movement: Mi-Go can move 9 meters/yards in a combat turn on the ground; 11 meters/yards while flying.


vs Lethal Damage: UNEARTHLY COMPOSITION – Mi-go are comprised of a spongy fungoid matter that absorbs some types of energy and morphs around kinetic shocks. If attacked with a traditional weapon or explosive that deals Lethal Damage, check to see whether the attack roll was an odd or even number. If odd, the Mi-go’s alien composition renders the damage ineffectual; if even, it is affected as per normal. A successful Lethality roll kills the creature.


Nippers50%, damage 1D6+2
Lightning Gun50%, range 20 yards, damage is electric shock. Can vary from simply STUN damage to Lethal 20% damage (see ELECTRO-PULSE WEAPON below). [Note that normal armor does not provide protection against electric shock].

Skills: Alertness 60%, Athletics 40%, Search 60%, Stealth 60%, plus numerous specialized scientific and technical skills, all at expert level (60%+).

LIMITED SHAPE CHANGING: The body of a Mi-Go can be reconfigured to a limited extent for its current activity. This takes a few minutes. No matter what a Mi-Go looks like from the outside, its inside remains a hideous fungal creature.

ELECTRO-PULSE WEAPONS: Mi-go Lightning Weapons can be set to varying intensity levels. At the lowest level, effect is limited to STUN. At the highest level, a successful attack delivers 20% Lethality damage. Whether struck by a low-powered or high-powered blast, any target that survives is effectively immobilized as their sensory and motor nerve center is paralyzed. Each subsequent turn, the survivor can make a CON × 5 test to shake off the paralysis and return to mobility next turn. Even after the immediate paralysis subsides, the victim suffers –20% on all actions for 1d20 turns. The human body is an excellent conductor of electricity. Anyone who touches the target of a Mi-Go Lightning Weapon attack will suffer the same effects.

THOUGHT TRANSFER: The Mi-Go usually communicate using telepathy. Without technical aids, they are unable to audibly speak. However, through a communication implant, they can understand and imitate human language.

SENSITIVITY TO LIGHT: Bright light is very uncomfortable for Mi-Go and they avoid it where they can, as it confuses their senses. In strong artificial light or in broad daylight, they receive a penalty of –20% on all tests.

ADVANCED TECHNOLOGY: Mi-Go have access to many different forms technology, each superior to anything humanity has developed. This includes Lightning Projection Weapons (see above) and Brain Cylinders (capable of keeping a human brain alive outside the body indefinitely).

RESILIANT TO PUNCTURE AND BULLETS: Damage from puncturing weapons and firearms is halved.

UNNATURAL ORGANISM: The fungal colony that serves as the physical body of a Mi-Go does not have any obvious weak points or vulnerable body areas. A CALLED SHOT to increase damage is therefore not possible, and critical success on an attack roll does not deliver double damage as normal. Their weird physical composition also makes them partially resistant to Lethal damage (see above).

SAN Loss: 1/1D8.


The Mi-Go are extremely intelligent. It is safe to assume that they have both economic and strategic goals on earth, where they are known to mine certain mineral resources. They would seem to have developed infrastructure, technology and suitable structures to support their mining activities. In some cases, they may even have entered into bargains or deals with corrupt human to help achieve their unknowable goals. In this way it is conceivable that some stray individuals might be acting as agents of the Mi-Go in human society.

Within our solar system, the Mi-Go’s primary base is the planet Yuggoth, which we call Pluto.

A second facet of Mi-Go behaviors is their intense scientific curiosity. Their biological experimentation extends beyond simple surgical manipulation of humans and animals. Indeed, given their extensive technological abilities and their outstanding knowledge of anatomy, biology, chemistry, etc., there is no end to the bizarre and clinical tests that the Mi-Go might carry out on terrestrial inhabitants.

The Mi-Go are known to worship some of the greater Unnatural Beings which comprise the Cthulhu Mythos. Most notably they demonstrate allegiance to Nyarlathotep, Azathoth, and Shub-Niggurath. It is possible that they are among the million minions of Nyarlathotep mentioned in some written accounts of the Unnatural. The same accounts hint at an enmity between the Mi-Go and a cult that reveres Hastur, with the latter cultists hunting down the fungi and eliminating them whenever the groups cross paths. Exactly why they do this remains unclear.

“The outer beings are perhaps the most marvelous organic things in or beyond all space and time-members of a cosmos-wide race of which all other life-forms are merely degenerate variants. They are more vegetable than animal, if these terms can be applied to the sort of matter composing them, and have a somewhat fungoid structure; though the presence of a chlorophyll-like substance and a very singular nutritive system differentiate them altogether from true cormophytic fungi. Indeed, the type is composed of a form of matter totally alien to our part of space — with electrons having a wholly different vibration rate. That is why the beings cannot be photographed on the ordinary camera films and plates of our known universe, even though our eyes can see them. With proper knowledge, however,any good chemist could make a photographic emulsion which would record their images.“
