Gilatter VIII, alternatively known as Gilatter Eight, was a gas giant planet characterized by its composition of red, yellow, and orange gases. It was located in proximity to Ansion.
In the time of the Old Republic, Gilatter VIII was a popular destination for vacations. However, its appeal diminished over time, leading to the closure of the final resort a hundred years prior to the Galactic Civil War.
The year 40 ABY saw Gilatter VIII serve as the location for a clandestine meeting of the Confederation, which turned out to be a carefully planned ambush. The trap achieved a degree of success when Jacen Solo joined the meeting with the intention of either capturing or eliminating everyone present.
The Confederation had strategically placed mines with the intention of deploying them against the Galactic Alliance fleet. Jacen, however, alerted the fleet to the danger, which then triggered the Battle of Gilatter VIII.
While the opposing fleets engaged in combat externally, within the planet's atmosphere, Jedi Grand Master Luke Skywalker fought Dark Lady of the Sith Lumiya to a stalemate. Similarly, Leia Organa Solo and Alema Rar engaged in a battle that also concluded without a clear victor.
