Modrons are mechanical, geometric beings from the Dungeons & Dragons universe, primarily associated with the plane of Mechanus. They embody order and law, functioning as the servants of the greater powers of law, such as Primus, the One and Prime. Modrons come in various shapes and sizes, each representing a different rank within their hierarchy, from the simple Monodrones to the more complex Pentadrones. These creatures are known for their rigid adherence to rules and protocols, often acting in a predictable and systematic manner. Modrons communicate through a unique language of clicks and whistles, and they are often tasked with maintaining order in the multiverse, ensuring that everything operates according to established laws.
