Hera is a largely agricultural world, considered the breadbasket for the entire system. Food is grown, processed, and packaged on Hera.
The planet is also the home of the infamous Serenity Valley, where the bloodiest battle of the war was fought. Lying midway between the Core and the outer planets on a major shipping lane, Hera was of great strategic importance during the war, making it an important staging ground for both sides. Taking Hera was key to winning the war, and Serenity Valley became the turning point for the conflict.
The war devastated Serenity Valley. The valley is still blackened and charred by the firestorm that swept through it. The only landmark is a graveyard on the hill next to the valley. Over half a million men and women – Alliance and Independent alike – are buried here, each with his or her own small identical headstone. Some have names. Most don’t. Serenity graveyard is one of the most hallowed and sacred pieces of ground in all the ’Verse.
