We have mastered the climate-controlled secrets of the Trebišnjica river system, the world's longest losing stream. By utilizing the stable temperatures and dry upper galleries of the ponors (sinkholes) during the summer, we have established a national network of subterranean granaries. This 'Hidden Reserve' ensures that our grain supplies are immune to the scorching Herzegovinian heat and, more importantly, invisible to the foraging parties of invading armies. While our enemies starve in a scorched valley, our forces remain well-fed by tapping into the earth's own cool depths, allowing us to maintain a high-morale standing army even during multi-year blockades.
