Rogue Modrons were originally outsiders from a lawful plane that were mortally injured on the Nyssian world and unable to continue with their unit. While their internal repair functions fixed them, they were abandoned and are now alone on an alien world.
They are self-aware mechanical units, built for a specific work function not social interactions. Being awkward, they rarely know what to do or say, thus they stand out in mortal communities. Knowing the importance of interaction, they try to fit in to the world by becoming members in lawfully-aligned or large social groups. Most often it's a lawful church (such as Quanna or Casna) or in a city's bureaucracy. From this point, they try to learn the social etiquette, history and culture of their adopted world and the people who they are with and follow the social rules.
If they do not reach an acceptable status point in a hierarchy organization after a certain amount of time, a Rogue Modron usually leaves and strikes it out as an adventurer, seeking fortune, fame and portals to other worlds. If they do reach mid-levels of authority, they are content, and subtlety try to influence law and order in the organization and the world around them.
When Rogue Modrons meet others of its kind, they are instant allies. They physically touch, and immediately share everything about their learning and their own individual pasts. They never engage in combat or take actions to directly interfere with their kin even if ordered to by their mortal comrades. It is common for Modrons to join with each other in a cause but never as equals, there must be one determined Commander. If they cannot determine among each other this strata - they cannot become partners.
The ultimate goal of a Rogue Modron is to find a portal back to their home plane. Strangely, if they find one, they are hesitant to go through as they are unsure of where or even if they will fit in with "True Modrons". There is no known instance of any Rogue Modron who ever returned back to their home world, so whether they are transformed, destroyed or celebrated is not known among non-kin.
