With success at both Barida and Todell, the Empire set their sights on the capital of Sekirol's Principality, Chiarn. Using Barida, a planet in close proximity to the capital world, as a staging point for the invasion, Task Force Nebula set off for Chiarn. Standing in the way of Nebula, however, was the INFERNO Cannon, stationed at Chiarn and ready for use. Upon Nebula's arrive, the Imperial task force quickly broke through the weak point in Chiarn's defenses, despite mounting casualties from both the Cannon and the Principality defenses.
