Xahean
The Xaheans were a humanoid species native to the planet Xahea, famous for their instincts. Their government was called the Xahean Council.

Their planet became highly politically relevant in the wider galaxy after a member of their royal family developed a way to recrystallize dilithium in the 2250s. (; )

Physiology and appearance
Xaheans were mostly humanoid, with sharp teeth and dark hands ending in clawed fingers, more pronounced in females then males. They had orbital sockets which could fracture; they had interior eyelids to the left and right of their eyes, invisible unless they blinked. Line-like patterns appeared on their faces, which might be blue or dark, and sometimes slightly raised. At least one Xahean wore a metal nose piercing. (; )

Xaheans apparently had the ability to affect technology from a distance, to turn themselves mostly invisible, and to erect spines on their backs. Their speech sounded like hisses and purring sounds. ()

Xahean circulatory fluid was blood-based, and orange in color. Its appearance varied from starkly luminescent to a duller, almost brownish tint. By the age of seventeen, Xaheans could be in a post-larval intermediate quiescent-stage of their development, which was akin to being a teen in a Human. (; )

History and culture
Xaheans believed that they had been born at the same time as their planet, and grown up at the same time as well. They believed they were the planet's twins. They considered themselves to be living in balance with the planet, a give and take.

In the 2250s, Me Hani Ika Hali Ka Po, sister of the then-king, invented a dilithium incubator. Unfortunately, this provoked a scramble among the Xaheans to gain warp capability, to the detriment of their homeworld.

Po, frustrated and frightened at the behavior of those around her, did not document or share her invention. In this period, Po's brother, the king, died, as did her mother. Her father was also dead. Shortly after the Xaheans developed warp drive, Po fled Xahea in defiance of her impending coronation as queen. She was convinced to return to lead her people after an encounter with Ensign Sylvia Tilly aboard the . ()

Other technology mastered on Xahea included a translator. ()

At least one Xahean lived on Earth in the late 24th century. ()

When the Human Adira Tal travelled to the dilithium planet in 3189, the holographic environment aboard the KSF Khi'eth caused them to appear in the form of a Xahean. ()
