During the era of the Infinite Empire, when the Rakata species invaded the Tython system, the gas giant Mawr, along with its many moons, became captured by the Infinite Empire. These celestial bodies were among the Settled Worlds located within that system. This conflict, taking place between 25,793 and 25,792 BBY, was preceded by an attack targeting the space station known as Fury Station. Around this same time, the Empire also captured the gas giant Obri. Following these events, the Rakata then struck at the planet of Tython.
The initial mention of Mawr's capture appeared in the comic book Dawn of the Jedi: Force War 1. This comic book was penned by John Ostrander and made available to the public on November 20, 2013.
