=== In ''Ravenloft'' ===
Illithids are the rulers of a domain in the ''[[Ravenloft]]'' campaign setting called Bluetspur, where their God-Brain is the [[Darklord (Ravenloft)|darklord]]. In the 5th Edition campaign guide ''[[Van Richten's Guide to Ravenloft]]'', it is revealed that an elder brain became diseased by discovering a "malignant truth" and it began to prey "upon its peers [...]. Horrified by an affliction that infected only them, the other elder brains united and psionically expelled the diseased brain from existence. Or so they thought. From a place without time or reality, the Dark Powers plucked the dying elder brain and planted it upon a tormented world".<ref>{{Cite book|url=https://www.worldcat.org/oclc/1238191930|title=Van Richten's Guide to Ravenloft|date=2021|isbn=978-0-7869-6725-4|location=Renton, WA|pages=73|oclc=1238191930|last1=Dragons |first1=Dungeons }}</ref> [[Polygon (website)|''Polygon'']] highlighted that Bluetspur is "a world of cosmic horror populated by malevolent mind flayers that will make your heroes question their own memories".<ref>{{Cite web|last=Hall|first=Charlie|date=2021-05-12|title=Van Richten's Guide to Ravenloft is the biggest, best D&D book of this generation|url=https://www.polygon.com/22430494/dungeons-dragons-van-richtens-guide-to-ravenloft-review|access-date=2021-05-23|website=Polygon|language=en}}</ref>

According to [[Ken Rolston]], the [[Beholder (Dungeons & Dragons)|beholder]] and the mind flayer "win starring roles as intergalactic menaces" in Spelljammer, describing the mind flayers as "evil, brain-sucking horrors who have polished up their social skills sufficiently to present a dubiously neutral facade to trading partners as they secretly scheme toward the day when all intelligent races will be their vassals and brain-food".<ref name="Dragon #154">{{cite journal| last = Rolston| first = Ken| author-link = Ken Rolston| title = Role-playing Reviews| journal = [[Dragon (magazine)|Dragon]]| issue = #154| pages = 59–63| publisher = [[TSR, Inc.|TSR]]| location = [[Lake Geneva, Wisconsin]]|date=February 1990}}</ref> ''D&D'' chroniclers Michael Witwer ''et al.'' commented on their appearance in the setting, already featured on the cover of ''[[AD&D Adventures in Space]]'': "the illithid, the race of the mind flayers, finally return home to space".<ref name=AA/>{{rp|224-225}}

=== ''Pharagos: The Battleground'' ===
In a proposed campaign setting, Pharagos is a lightly populated [[Earth]]-like world with three continents and numerous chains of islands. The one remarkable feature of this world is the presence of an immense petrified corpse of a god previously worshiped by the Forerunner civilization before it was crushed by the illithid empire. A vast stony column of forgotten beliefs, it is buried deep in the ground. The current inhabitants of Pharagos have no knowledge of the planet's past; the illithid empire's rule over Pharagos and the origin of the gith races on this world are lost to history. They are unaware that the source of mystical power for their numerous cults comes from the presence of the dead god under their land.<ref>[[James Wyatt (game designer)|Wyatt, James]] (July 2003).
