Gith

Githyanki are generally found in the Deadlands as Bandits or Raiders

the Githzerai are generally found within the Scalect Dominion

Githyanki:

 * Trained Mind: The Githyanki creches are cruel, but comprehensive, and they teach their students how to travel the Astral Plane. Once you reach 5th level, you can cast the misty step spell once per long rest. Once you reach 7th level, you may cast the nondetection spell once per long rest, targeting only yourself. These abilities count as Psionic. Intelligence is your spellcasting ability for these spells and for the other spells you know from the Psionic Power ability.
 * Martial Prodigy: You are proficient with light and medium armor and with shortswords, longswords, and greatswords.
 * Decadent Mastery: You learn one language of your choice, and you are proficient with one skill or tool of your choice. In the  city of  Malkice, githyanki have bountiful time to master odd bits of knowledge.

Githzerai:

 * Focused Mind: Githzerai revere discipline, and they teach their students to harness the power of the will to wield their natural psionics. Once you reach 5th level, you can cast the see invisibility spell once per long rest. Wisdom is your spellcasting ability for this spell and for the other spells you know from the Psionic Power ability.
 * Mental Discipline: You have advantage on saving throws against the charmed and frightened conditions. Under the tutelage of monastic masters, githzerai learn to govern their own minds.
 * Mind Strikes: As an action, you can emit a psychic burst to jar enemies around you. Creatures within 10 feet of you must make a Intelligence save against a DC of 8 + your Intelligence modifier + your proficiency bonus. A creature that fails the save takes 2d6 psychic damage, and half as much damage on a successful save. The damage increases to 3d6 at 6th level, 4d6 at 11th level, and 5d6 at 16th level. After you use your Mind Strike, you can't use it again until you complete a short or long rest.
