Pendulum System

The Pendulum system was one of the early systems colonized following the revolutionary engineering feat of the Shaw-Fujikawa Translight Engine. The system's most noteworthy feature was the gas giant of Callahan which parented four mostly habitable moons. Becoming known as the Callahan Moons the up-and-coming colonial system relied heavily on one another for trade, resources, and support in the great unknown. The advantage of having one another to rely became paramount in the later establishment of the Callahan Industrial System where the moon system became a thriving and booming system of industry. Established in 2319 the Pendulum system would become vital in establishing further out colonies into the future.

Callahan Moon System
Featuring four similarly sized and mostly habitable moons the Callahan gas giant was the anchoring point for a thriving colony for Humanity. The moon system eventually became a booming industrial center for early efforts into the frontier of colonization.

Callahan Moon Terror Event
Sometime after the onset of the Inner Colony Wars after 2362 the Callahan moon system which was an up and coming star of industry was victim of a large scale terror event. It is important to note that early colonization while selective, was still relatively lawless in the sense that space was still wildly expansive and Humanity lacked many of the essential legislative and technological achievements to appropriately monitor and police any outlaw activity.

During the Inner Colony Wars terrorist agents were able to infiltrate the system and detonate several dozen excavation grade munitions within the industrial centers across the moons. Previously the moon system had been far from the fire storm of the inner colony wars and thus the terror event triggered a large scale refortification of the limited UNSC forces. The Aeolus-class cruiser was crucial in repelling the attack and forcing the terror cell out of the system.
