A reserved species by nature, Grey culture revolves around the pursuit of intellectual enlightenment. To that end they have developed rapid means of interstellar travel, allowing them to quickly traverse the stars in their quest for greater Metaversal knowledge. Their civilization spans numerous systems, and is divided loosely into two main cooperative sects: those driven to increase their knowledge of all things spiritual, and those engaged in scientific discovery.
Some time ago, whilst exploring the concept of consciousness, the Greys managed to create a race of mechanoids that gained full sentience: the Robotrons. This new race has consequently evolved autonomously, developing a new and unique culture, it's members integrating with the neapolitan communities spanning the bounds of Federation space.
