Taragon

Taragon was a class M planet located in the galaxy's Alpha or Beta Quadrant and hosted a Federation colony.

History and specifics
In the 2240s, Taragon was colonized by Humans. The planet had a wealth of mineral resources, and the colony spent decades preparing to mine them.

In the 2260s, as mining progressed deeper into the planet, it unknowingly disturbed areas occupied by the Taragon lifeform. In 2266, it retaliated by triggering natural disasters including volcanic eruptions. Distress calls from the colony were picked up by the Federation starship USS Enterprise (NCC-1701). James T. Kirk and Spock reconnoitered outside of a city in search of evidence of intelligent lifeforms capable of telepathy that could explain a rash of insanity among the colonists, eventually discovering the Taragon lifeform and figuring out how to communicate with it. In exchange for its protection, it agreed to help fashion new buildings and equipment for the colonists.
