The Merraxen were an ancient race of peoples whom originally inhabited Korriban, however, later immigrated to Graef due to in fighting. This race thrived in the days prior to the Old Republic and continued to remain strong until the Great Galactic Civil War. The Merraxen had a natural connection with the Force and worshipped the dark side, which they dubbed Underlord. It was largely due to their Force-sensitivity that they became some of the greatest warriors of their time. In many ways, the Merraxen were ahead of their time, creating primitive lightsabers and building giant, Force driven spacecrafts. However, in the end it was this power that would destroy them from within. After a bloody civil war, the followers of the triumphant warlord traveled to Graef. There they set up a new empire.
