The Mason's of Caldari Prime were once a very strong and powerful corporate family. However, when the family were split due to 'political' differences, Croncy and Atamarashi Mason, the two oldest brothers in the family, began their own spacefaring freelance company. Later they were approached by an entity known as Magnasis. This leader gave them opportunities to build their eventual empire, and conquer the traitors in their family.
