In my last post I pointed out that the Shadow Monster of Stranger Things is much closer to an aboleth than a mind flayer. Since then I found an interview with the Duffer Brothers, who claim they designed the Shadow Monster without thinking of any creature from D&D, whether aboleth or mind flayer. This is how they tell it:
Matt: We came up with the creature and it was always called the Shadow Monster. Then we were like, “We need to come up with a proper name for this thing.” When we were going through the Dungeons & Dragons manual, I found this creature I’d forgotten about called the Mind Flayer. It was so close to the idea of our Shadow Monster. It was eerily the same. We were like, “Well, we’ve got our name.” It’s a weird-ass name, but the Mind Flayer it is.
Ross: It has nothing to do with the shape, or the way it looks, or the particles. But the fact that it moves from dimension to dimension, infecting the minds of others in order to control them and spread itself. I can’t remember everything else, but it’s everything that we were talking about with our Shadow Monster. I don’t think anyone will believe us. They’re going to think we just, day one, looked through the Dungeons & Dragons manual. I don’t know why we didn’t. But we did not.
Actually, yes, I thought the Duffer Brothers were looking through the D&D manuals, but taking clear inspiration from the aboleth, not the mind flayer. The Shadow Monster is so close to the aboleth you have to be trying to not see it. I assumed the Duffers called their creature a mind flayer because it sounds bad ass, even to an audience unfamiliar with Dungeons & Dragons. “Aboleth” sounds unimpressive by comparison, like something you’d find listed in an obscure academic journal. I have a hard time believing the D&D-savvy Duffer Brothers designed a creature that fits the aboleth almost to a tee but were unaware of it.
For the fun of it, I researched the evolution of both the aboleth and mind flayer in D&D. I’ve bolded all the relevant parts that bear any resemblance to the Shadow Creature of Stranger Things. I’m not sure what Ross means about the mind flayer’s ability to “spread itself” in the 1st edition Monster Manual. The hive mind aspect of the mind flayer was not introduced into the game until the late ’90s (see below), and certainly not in the manual Dustin reads from.
The Mind Flayer
1975. The Strategic Review #1 introduces the mind flayer: a humanoid with an octopus-like head that feeds on brains. The creature’s physical attack is by striking a victim with its four purplish black tentacles. If a tentacle hits it will reach the victim’s brain in 1-4 rounds and draw it forth, immediately killing the creature. The mind flayer then devours the brain. It can also unleash a mind blast in a 60-foot cone range, which causes death, coma, sleep, stun, confusion, or rage, depending on the victim’s intelligence.
1977. The Monster Manual canonizes the mind flayer, expanding and changing details provided above in The Strategic Review. Notably, the mind blast is now a simplified psionic blast which stuns, regardless of the victim’s intelligence. The mind flayer has the psionic abilities of domination, levitation, ESP, body equilibrium, and astral projection/probability travel. The domination ability allows it to control a victim (if a saving throw fails) as long as the mind flayer keeps concentrating on the victim. It’s also now specified that mind flayers detest sunlight and prefer habitats of subterranean places.
1981. Dwellers of the Forbidden City introduces the aboleth: a gigantic tentacled monster that has strong psionic powers, and uses its mind control ability to make slaves. It’s an ancient life form, extremely intelligent, and views all other races as inferior upstarts who stole what is rightfully theirs. It attacks with its four tentacles which cause l-6 points of damage each, in addition to changing the victim’s skin into a clear slimy membrane in 2-5 rounds if a saving throw fails. Once the change is complete, the membrane must be kept damp with cool water or the victim will take 1-12 points of damage each turn due to intense pain caused by the drying membrane. (This is somewhat reminiscent of the way Will Byers needed to be kept cold.) It’s an amphibious creature, and in water it will secrete a cloud of mucus all around its body. Any creature drawn into the mucus must save vs. poison or it will inhale the stuff and become unable to breathe air, suffocating in 2-12 rounds if trying to breathe air. However, that same creature will gain the ability to breathe water, as a potion of water breathing, for 1-3 hours. The aboleth uses this mucus to give its slaves the power to breathe water. (The mucus reminds of the gooey substance from the Upside Down. Does that goo allow one to breathe the toxic environment of the Upside Down?)
1983. The Monster Manual II canonizes the aboleth, detailing them exactly as described above in Dwellers of the Forbidden City.
The Mind Flayer
1983. “The Ecology of the Mind Flayer”, in Dragon Magazine #78, offers the first suggestion that mind flayers are from another world. It emphasizes their brain-eating and domination powers in much stronger terms:
“To eat the brain of another race is the ultimate symbol of dominion over that race. They consume that which is important to them. Their tentacles have bony ridges that cut flesh and bone with ease, exposing the inside of the skull. Many collect the skulls of their victims and adorn their bodies with the trophies. They have a psionic power that especially helps them achieve their evil ends — a power of domination that they use with pleasure on their victims and those who would attack them. This domination power allows the mind flayer to control every movement of a single victim, to an unlimited extreme. Once, on a raid to an illithid lair, I saw a githyanki captain run himself through with his own sword while under the control of one of them.” (p 67)
So now the mind flayer can dominate to “an unlimited extreme”, even if the results are fatal to the victim. As presented in The Monster Manual, the domination power was the standard psionic ability and not as powerful. However, the mind flayer must still concentrate on the victim at all times, unlike the aboleth.
1988. “The Ecology of the Aboleth”, in Dragon Magazine #131, presents variants that are more powerful than the common aboleth: greater aboleth (who maintain slaves gathered by the common aboleth), noble aboleth (who conduct scientific research and experimentation), ruler aboleth (who command aboleth cities or areas, and have a mental link with all their subjects), and a grand aboleth (a godlike creature that dwarfs even the rulers, but existing only in rumors). The hive mind is introduced as an aboleth feature, in the rulers, who are described as follows:
“These huge, bloated monstrosities are the largest and most intelligent of all aboleth (aside from the grand aboleth). Its telepathic link with its subjects allows it to be constantly aware of everything going on in its realm. Rulers are, in most other respects, similar to common and greater aboleth. They possess enslavement abilities equal to those of greater aboleth and can generate veil spells at will. Rulers can generate slime in a 5-foot radius, and the mere sight of one causes fear in all beings of less than 5th level or five hit dice.” (p 38)
It’s now specified that aboleth reproduce by egg, which are covered in a thick slime. The eggs hatch mini-aboleth who take about ten years to mature into adult form. (The demogorgon of Stranger Things reproduces by tentacle implantation (as it did to Will’s throat), not egg, so the eggs seen in season 1 were probably eggs for shadow monsters (“aboleth”) rather than demogorgons.)
The Mind Flayer
1998. The Illithiad reveals the world the mind flayers come from, a realm called the Outside. They reproduce by egg, which hatch tadpoles until they grow and are implanted into the brain of another humanoid, after which it immediately subsumes the creature’s personality, replacing it with its own awakening intellect. The hive mind is introduced as a mind flayer feature, which is called the “Elder Brain”. An elder brain is the final stage of the mind flayer life cycle, composed of the brains of long-dead mind flayers. It lives in a brine-filled pool in the center of a mind flayer city, where it guides its community by filling mind flayers with dreams of perverse domination. It has the psionic abilities of other mind flayers, but physically it is weak (unlike the powerful ruler aboleth and Shadow Monster from Stranger Things), which is why mind flayers protect their elder by securing it in well-protected caves. The elder can communicate telepathically not only with its subjects, but with any creature within 350 foot distance. The ultimate goal of a mind flayer is to sacrifice its brain as it nears the end of its lifespan, by merging with the elder brain, strengthening the elder’s powers and intellect. Most mind flayer are unaware, however, that their personalities and consciousness are lost when joining with the elder brain, leaving only their knowledge and ideas to survive. (A closely guarded secret kept by the elder brains.)
As I said before, it’s clear that the aboleth are the closer representation of the Shadow Monster, though obviously “mind flayer” sounds sexier and was the better marketing choice. The hive mind is an anachronism for both, though it was developed first for the aboleth (in the ’80s) and only much later for the mind flayer (in the ’90s).
