Mishra’s Self-Replicator

In modern-day Dominaria, the events of the Brother's War are a distant memory from 4000 years past, before the time of nearly any living creature on Dominaria. The record of the war's events in the minds of modern Dominarians is tenuous at best, but remnants of the Brother's War still linger in Dominaria, both in the shape of its geography and in forgotten relics.   Among these relics are the Brother's lost labs- factories, workshops, and studious that Urza and Mishra built to fuel their battle, and to which they never returned. Most famous among them is Mishra's many factories, self-running assembly lines built to create everything from weapons to soldiers, designed to work entirely without outside interaction. And though the war ended and Mishra was defeated, his factories continued without him. Even to this day, buried beneath dozens of layers of forgotten history, some of Mishra's project still survive.   Built to Last Over the nearly thirty-five year course of the Brother's War, both Urza and Mishra constructed wonders of artifice that remain unrivaled in the modern age. And among Mishra's proudest accomplishments were his artificial army of self-replicating soldiers, constructs designed to build and rebuild themselves them and again- ensuring the artificer would always have an army at his back when he faced his brother on the battlefield. The artificial soldiers magical programming was so powerful, that even today they continue the process, building new bodies for themselves each time their previous work fails.   The modern-day people of Dominaria call them self-replicators, and with each passing year, sightings of the constructs grow more and more rare. The self-replicators are born in Mishra's abandoned factories, and to the fatories they must return to build themselves new bodies. Once a quick and easy job, whatever resources the self-replicators had to work with have long since dried up, leaving them to search Dominaria for the supplies they require. This act of attempted self-preservation takes up most of their time, and a self-replicator might travels hundreds of miles and spend a year or more looking for what it needs. Once the parts are collected, requiring 1000 GP worth of materials, the self-replicator can build its new body, which takes one week of non-stop work.   For some self-replicators, they are only construct left in a factory that might have one housed hundreds. Some spend so much time searching for what they need to rebuild their new bodies that, by the time the work is finished, the metal plating of their current home is already beginning to rust, succumbing to the harsh workings of time. Once their work is completed, and their new bodies finished, they might have only a few weeks or days before they collapse, and their work starts itself all over again, taking just a little bit longer than the last time, pressing them closer and closer to a deadline hey might one day fail to reach.
