Terlina system

The Terlina system was a remote planetary system that was located somewhere in the Alpha or Beta Quadrant.

This system had at least three planets. In the system's habitable zone, there was the planet Terlina III.

After the destruction of the Omicron Theta colony in 2338, Dr. Noonien Soong and his wife Juliana re-settled on Terlina III.

In 2367, Data brought the USS Enterprise-D to this system in response to Dr. Soong's summoning signal. Lore also arrived at the system aboard his ship. (TNG: "Brothers", "Inheritance")

In the script for "Inheritance", the pronunciation for Terlina is "tur-LEE-nah". [1]
The identity of Soong's star system was not revealed until "Inheritance".
