In 2364, Ligon II was orbited by an orbital control station and was the source of a rare vaccine that was needed on Federation planet Styris IV. The USS Enterprise-D visited the planet to attempt to secure some of the vaccine, and in the process Lieutenant Yar was kidnapped.
The Ligonian Centerplace, an imposing structure overlooking a village, was the place were the ruler of Ligon II, Lutan, and later Hagon in early 2364, resided. The Centerplace was located on the northern hemisphere of the planet, close to an ocean.
It was characterized by a large tower in the center of the structure and a large open courtyard, with a small fountain in the center. Lutan's throne was located on one end of the courtyard; a large wall of hand-held weapons, including crossbows and spears, was located on the other side. Two sentries were often standing guard next to two giant gongs, which were located close to the fountain.
The Centerplace was adorned with many different plants and the characteristic, hexagonal shape of the Ligonian logo was present everywhere, including on doors and the weapon wall.
A fighting range consisting of different levels of steps, lights, and metal rods could be installed in the middle of the Centerplace. Yareena, Lutan's First One, fought Natasha Yar on this structure in a fight to the death. Several seats were arranged around the fighting range for spectators to attend the ceremony.
