The Republic of Demond was formed on the 4th of Reylin, 2438 2E, near the end of the 2nd Era. After the plague of Were-Beasts from the North scattered the many tribes of Men from the region, Harmon Delmond led his people southward, escaping to what initially seemed greener pastures.
But despite the verdant valley, the lands were teeming with reptilian creatures only spoken of in myth. These creatures (now known as the Scale-Kin) attacked in an effort to repel the newcomers. Delmond knew he could not return north, so he militarized his people and waged a 2 year war against the Scale-Kin that would end in their removal from the land, pushing them southward into the swamps.
This victory marked the foundation of the Republic. For the next several hundred years, the Republic would grow to become one of the most successful societies of Men in all of Western Brilanor.
