Talaxian
The Talaxian is a humanoid civilization in the Star Trek universe native to the planet Talax in the Delta Quadrant. The Talaxians surrendered to the Haakonian Order in 2356 after a decade-long war was ended by the deployment of the metreon cascade, a deadly weapon that killed over 300,000 Talaxians on Rinax. Talaxians who came in contact with the fallout from the metreon cascade suffered metremia, a deadly blood disease.
The Talaxian respiratory system is directly linked to multiple points along the spinal column.
It is a tradition in Talaxian society to share the history of a meal before eating, as a way of enhancing the culinary experience. It is also tradition for Talaxian proper names to contain the letter x.
