Manual (1993). The ulitharid, or "noble illithid" was introduced in the Dungeon adventure Thunder Under Needlespire by James Jacobs in Dungeon #24 (July/August 1990), and later included in the Monstrous Compendium Annual One (1994). The Complete Psionics Handbook (1991) presented ways on using mind flayers with psionic powers. The alhoon, also known as the illithilich or mind flayer lich, was introduced in the Menzoberranzan boxed set, in the booklet "Book One: The City" (1992). The book The Illithiad (1998), and the Monstrous Arcana module series that accompanies it, greatly develops the mind flayer further. The Illithiad introduced the illithid elder brain and the illithid-roper crossbreed, the urophion. The module Dawn of the Overmind featured an origin story for the illithids. Dungeons & Dragons 3.0 edition (2000–2002) The mind flayer appears in the Monster Manual for this edition (2000). Savage Species (2003) added the mind flayer "racial class", allowing Mind Flayers to be played from level 1 onward until they reached parity with normal Mind Flayers, and added the "Illithid Savant" prestige class. Dungeons & Dragons 3.5 edition (2003–2007) The mind flayer appears in the revised Monster Manual for this edition (2003), in both playable and non-playable forms. One of the differences between the playable Mind Flayer in the Monster Manual and the Mind Flayer racial class in Savage Species is that the racial class has only itself as a favored class, while the normal Mind Flayer has wizard as a favored class. The mind flayer received its own chapter in the book Lords of Madness: The Book of Aberrations (2005). The Expanded Psionics Handbook (2004) re-introduced the psionic mind flayer, detailing the differences between psionic and normal mind flayers, although creating a Psionic Mind Flayer still requires the information from the Monster Manual. Monster Manual V (2007) introduced the concept of "thoon", a driving force (be it some alien god, outside philosophy, or other driving incentive) which has changed several mindflayers' world outlooks. Dungeons & Dragons 4th edition (2008–2014) The mind flayer appears in the Monster Manual for this edition (2008). Dungeons & Dragons 5th edition (2014–present) The mind flayer appears in the Monster Manual for this edition (2014). Additional information about the mind flayers is found in Volo's Guide to Monsters (2016). The information includes details about their origins, their reproduction, their dispositions and behaviors, and their elder brain. The book also details this edition's Alhoon, Ulitharid, Mindwitness and
