Alternate reality
James T. Kirk addressing the Teenaxi Delegation
The Teenaxi Delegation (or Teenax Delegation) was the governing body of the Teenaxi. Their homeworld was Teenax.
In 2263 of the alternate reality, they rejected a peace offering from the Fibonan High Council, consisting of a piece of an ancient weapon called the abronath, a fact recorded in the Federation archive shortly thereafter. (Star Trek Beyond)
This organization is referred to in dialogue as the "Teenaxi Delegation" but called the "Teenax Delegation" on the Federation archive computer display.
