Kwah-kai, also known as "Little Hands" (which presumably is what Kwah-kai translates to), are red-striped and yellow-eyed simianoids indigenous to the planet Aiur. Ever curious beings, they are considered clever and will steal unattended items which they find interesting in a manner similar to monkeys on Earth.
During the Aeon of Strife, the Kwah-kai featured in cautionary tales of the Shelak Tribe, as to what would happen to them should they grow too curious and indulge their tendencies. Savassan and Temlaa were two exceptions, whom admired the Kwah-kai for their curious nature.
Because of the planet Aiur's fall to the Zerg and no references being made to their being brought off-world, they are currently considered extinct until proof of their further existence has revealed itself.
