The Githyanki (also known as the Gith, or "them damn Yankis") are an evil race in the Dungeons and Dragons setting, and look like either emaciated, jaundiced elves or some horrible cross of elf and goblin, depending on the edition. The Githyanki are classic 1st edition monsters; as denizens of the original Fiend Folio, they first appeared in the pages of Dragon Magazine -- in fact, they showed up back in issue number 12, back in 1979.
The githyanki are the twisted, estranged kin of the githzerai, divided from their cousins by a philosophical breach that occurred centuries ago. To recap, the original Gith-kin were humanoids (and/or humans) who were enslaved and mutated by the Mind flayer empire for untold generations, until two figures rose up and led their people in a massive slave uprising; Zerthimon the mystic, and Gith the warrior-woman. At the brink of total illithid annihilation, Gith began planning to "truly" free her people by... well, basically enslaving every other race and making the Gith-kin as bad as the illithids had been. Zerthimon objected to this, an act called the Pronouncement of Two Skies, and thus the illithid's former slaves were divided into "Those Who Spurn Gith" (Githzerai) and "The Children of Gith" (Githyanki), with the former bogging off to Limbo (or the Elemental Chaos) and the latter disappearing into the Astral Plane.
Gith herself disappeared after a trip to Baator to secure an alliance with the dragon-goddess Tiamat, but one of her greatest warriors, Vlaakith, took her place as Warrior-Queen of the Githyanki and kept her people on the path that Gith had said. More than one person has wondered if Vlaakith didn't betray Gith in some way, earning the pact with red dragons by, say, feeding Gith to Tiamat, but the githyanki won't hear of it.
In fact, githyanki don't like to hear a lot of ugly things about their race, mostly because they're all true. The first and foremost is that they're a bunch of hypocrites, who are so obsessed with "being free" that they have become convinced their manifest destiny is to conquer & enslave every other race in the multiverse.
Secondly, they get really snippy if one notes that their practice of raiding Astral communities, taking a certain amount of the goods and then leaving in a form of "sustainable pillaging" is essentially a master-slave relation dressed up in piracy clothing. See, although the githyanki aren't completely dependent on raiding to survive, the simple truth is that their choice of residence and their war-focused culture means they can't produce enough food, goods and other essentials to support their own population. And, if they steal everything from the astral villages they raid or ships they rob, then they'll ultimately starve to death because those sources of goods will either die out or stop coming where they can get them. So, they steal the bulk of the goods from their victims, do as little damage as they can, and let them scrape a living until eventually they have enough of a stockpile to make robbing them profitable again. But, if you ever point out that this basically makes them slave-owners collecting their serfs' taxes in a very dramatic way, they'll immediately kill the entire band they were robbing from in order to "prove" they're not slave-owners. Yeah, they're not the smartest race in the multiverse by a long shot.
Mind you, this "we're not slavers, honest!" thing varies a little depending on edition/cosmology; in the World Axis, Tu'narath is home to a sizable population of slave-farmers who exist to try and cultivate food for their githyanki masters - and who are summarily eaten by both the resident dragons and the githyanki themselves when they are used up.
And, finally, don't call them out on how they preach total freedom for themselves, but in reality they've become nothing but a race of warrior-slaves for their "divine" god-queen. Oh, yes. See, Vlaakith was so beloved by the first githyanki that they made her daughter their ruler, and her daughter, and her daughter, and so on, an unbroken line of god-queens that lasted until Vlaakith CLVII (that's Vlaakith the 157th, if you don't know your Latin numerals). She never had a daughter, but she turned herself into a lich, so it's all good; now she can reign forever as an immortal, undying tyrant.
If you need more proof that the githyanki have turned themselves into slaves and never even realized it; one of the drawbacks of being a lich (or at least a githyanki lich, depending on edition) is that Vlaakith CLVII needs to eat souls on a regular basis to sustain herself. More importantly, she's terrified of being ousted from power by a stronger githyanki even though they've been worshipping her and adoring her for generations. So, she solves both problems by making it a simple cultural practice that when a githyanki gets powerful enough, they are granted the "honor" of having her eat their souls. And the githyanki are so mindlessly loyal to her that they actually do consider this an honor!
Interestingly, the 4th edition article on Tu'narath and githyanki society explicitly states that this has had serious negative effects on githyanki society, and that Vlaakith's actions are basically pushing her people to be made up of the mediocre. Which is harming their race's long-term goals.
Fifth edition, in Mordenkainen's Tome of Foes, which devoted an entire chapter to discussing the gith race, instead reframes or reflavors most of the above. Rather than explicitly eating her people's souls when they get too strong, Vlaakith is sort of deliberately holding them back, preventing any one of her lieutenants from gaining too much experience and power and so overthrowing her. And because they live in the Astral Plane, where no one ages and time has no meaning, the githyanki are instead basically jaded war-hipsters, spending all the time they aren't fighting or raiding bored out of their fucking minds and desperate for some novelty as they futz about their decadent metropolis of a city toying with various hobbies without ever really getting into any of them. Thus, as Mordenkainen himself notes, Vlaakith's system does a great job of churning out indoctrinated fanatics without actually creating people fit for doing anything useful.
Also, rather than taking slaves for slavery's sake, they mostly just abandon or kill captives who have no extrinsic value, though there is a small community of random people they've kidnapped living in a slum of the great city.
Aside from their practice of flying around on red dragons, githyanki are most known for two things in terms of combat ability.
Firstly, githyanki are big believers in the concept of multiclassing, with a long tradition of fighter/wizard combatants. Indeed, the idea of the warrior-mage is so iconic, and so associable with the githyanki, that their culture's name for it - the Gish - has been adopted as a general term in greater /tg/ culture. Well, the alternative was the githzerai term "Zerth", but that wasn't as catchy.
Secondly, their most iconic weapon; baroque greatswords forged of a strange, silvery metal native to their extraplanar environment. Known simply as Silver Swords, or, at most, Githyanki Silver Swords, these weapons are uniquely suited to fighting people who are using astral projection, as they can cut the "astral thread" of these people which is, generally, instant death (ironically, less lethal in 1e, when it just booted you back to the material). The other bonuses of the Silver Swords varies from edition to edition; in 1e, they were sentient +3 weapons that weren't very smart, but did have nebulous other magical powers. In 2e, they lost their sentience, but there was also a "Greater" version that was a +5 weapon and a Vorpal Sword in addition to its astral cord-cutting and it could cut the threads of people under the Mind Bar power. In 3e, they were initially downgraded to +1 weapons that could potentially nullify a victim's psionic abilities for 1d4 rounds, but in the Psionics Handbook, the classic +3 astral cord-cutters and +5 vorpal versions returned. 4e gave them the ability to convert damage dealt with them into the Psychic type, gaining the feat support that brings, and 5e made them into just +3 weapons. Needless to say, githyanki are extremely protective of these swords and will go to almost any length to retrieve them.
Needless to say, being that they are huge dicks and pretty much all willing slaves to their evil god-queen, githyanki aren't traditionally considered suitable for PCs, unlike their Githzerai cousins, who were actually in the first wave of Planescape PCs, alongside the Tiefling and the Bariaur. They do, however, have PC writeups in the Expanded Psionics Handbook and Polyhedron Magazine #159 for 3.5, and in the Monster Manual for 4e.
In D&D and 5e, the githyanki have a particular interest in the material plane; not just because it's where they go to hunt illithids, but because nothing ages on the Astral Plane, so they need to lay their eggs (yeah, they do that) and rear their children on the prime so they can reach maturity.
They were also the subject of a pair of epic, edition-spanning campaigns; 3.5 gave us Incursion, a combination adventure path/campaign setting spread over the pages of Dragon Magazine #309, Dungeon Magazine #100, and Polyhedron #159, in which the players fight against a githyanki conquest of their home world, and 4e gave us a sequel in Scales of War, which ran from Dungeon #156 to Dungeon #175.
These adventures introduced the Duthka'giths; fiendish half-red dragon githyanki bred at Vlaakith's creation, and the source of considerable consternation from many other githyanki despite the eons of loyal partnership between the two races.
Given their rather heavy-handed "Always Evil!" setup, it goes without saying that Githyanki have been rather absent from the line-up of PCs. Still, D&D really does have a solid tradition of Monster Adventurers, and so whilst the githzerai get all the press, the Githyanki have been playable since AD&D too.
The first appearance of githyanki PCs was in "A Guide to the Astral Plane", which admitted that rogue githyanki are a possibility and not all of them fall for Vlaakith's efforts. Their writeup looked like this:
- +1 Dexterity, +1 Intelligence, -1 Wisdom, -1 Charisma
- Racial Maximums of 19 Dex and Int
- Class Restrictions: Fighter, Mage, Gish (Fighter/Mage), Psionicist
- Astral Movement rate of 96
- Double odds of having psionic wild talents
- Same access to psionic Sciences and Devotions as humans
- Malign Reputation: -2 reaction penalty with Good NPCs, -1 reaction penalty with Neutral NPCs
- Racial Enmity: Githzerai: -8 reaction penalty with Githzerai, stacks with Malign Reputation
- The Lich-Queen Is Watching: Upon hitting 11th level, the PC has Vlaakith CLVII's attention; if they reach 12th level, she senses it and will dispatch several waves of githyanki "retrieval teams", then turn to local resources (assassins, etc), not stopping until either she or the githyanki character is dead. Githyanki can choose to deliberately not gain any levels after 11th to avoid her wrath.
In 3.5, your Githyanki writeup looked like this when it appeared in the Expanded Psionics Handbook:
- +2 Dexterity, +2 Constitution, -2 Wisdom
- Base Land Speed 30 feet
- Darkvision 60 feet
- Naturally Psionic: Increase your Psionic Points Pool by +3 psi points.
- Psi-Like Abilities: At 1st level, you can use the Psi-Like Abilities of Far Hand and Psionic Daze 3/day each. You also gain the Psi-Like Abilities of Concealing Amorpha (3/day) at 3rd level, Psionic Dimension Door (3/day) at 6th level, before finishing with Telekinetic Thrust (3/day) and Psionic Plane Shift (1/day) at 9th level.
- Power Resistance: Hit Dice + 5
- Favored Class: Fighter
- Level Adjustment: +2
Polyhedron's writeup was similar, but different: it replaced the Naturally Psionic and Psi-Like Abilities with "Psionics", replacing its psi-like abilities with the spell-like abilities of Mage Hand (3/day) and Daze Humanoid (3/day) at 1st level, Dimension Door (3/day) at 6th level, and both Telekinesis (3/day) and Plane Shift (1/day) at 9th level. Likewise, Power Resistance was replace with Spell Resistance (5 + 1 per character level) and they gained the Extraplanar trait, making them vulnerable to Banishment and similar spells when outside of the Astral Plane.
Over in 4th edition, although arguably somewhat weaker than many other 4e races due to being in the back of the Monster Manual 1, githyanki were a lot less of a hassle to play with and still surprisingly viable:
- Ability Scores: +2 Constitution, +2 Intelligence
- Size: Medium
- Speed: 6 squares
- Vision: Normal
- Skill Bonuses: +2 History
- Danger Sense: +2 bonus to Initiative checks.
- Githyanki Willpower: +1 to Will defense, +2 to saving throws against Charm effects.
- Racial Power - Telekinetic Leap: Usable 1/Encounter, Move Action, target Self or 1 ally within 10 squares. The target of this power can Fly up to 5 squares; if you use this on an ally, that ally must remain in your line of sight at all times during the effect.
In 5th edition, githyanki resurfaced in the September 2017 issue of Unearthed Arcana, with results that were... different to what'd come before, but technically also more of the same. Weirdly, while both subraces clearly got the shaft in terms of being designed by people who actually cared about the race in question, they're significantly more powerful and in-line with the majority of other 5e PC races compared to their poor, more PC-friendly cousins:
- +2 Strength, +1 Intelligence
- Speed 30 feet
- Vision: Normal
- Decadent Mastery: One free language proficiency and one free tool or skill proficiency of your choice.
- Martial Prodigy: Free proficiency with Light and Medium Armor.
- Githyanki Psionics: Mage Hand at-will, Jump 1/day at 3rd level, Misty Step 1/day at 5th level, all keying off of Intelligence.
Gith PCs were used in a teaser adventure previewing the Tome of Foes, letting fans get an early look at the official version. The only real difference for githyanki was that their Martial Prodigy feature now gives them Proficiency in the Shortsword, Longsword and Greatsword, which after all are as thematically tied to their race as the axe & hammer are to dwarves or the longsword & bow are to elves.
The Githyanki's backstory is basically same as the Ur-Quan Star Control
