Meanwhile, underground...
Dememoras's armies were comprised mostly of Dracons. He changed them, but they were still the same beings at their cores. What many did not know was that much of the day-to-day labor of the armies was taken care of by colonies of kobolds. Numbering over a million, these little creatures were impressed into service for Dememoras, largely by fear and by a desire to "be on the right side." Kobolds were a numerous race, known for their mining skills and fast breeding. Shaped like small bipedal lizards, adventurers and soldiers alike considered them to as much an annoyance as anything else.

Standing only at about half the height of a human or dracon, they were little threat, except in overwhelming numbers, and even then, they required good weapons, leadership, and frequently, some form of magical enhancement to be a serious danger. The kobolds in the Dracon lands numbered about 3 million, which was still less than 10% of the population of the Dracons themselves. About 1 in 3 kobolds served the evil forces loyal to Dememoras, although they didn't know his name. References to "the unknown master" or "the dark master" abounded, but these were dismissed as references to a deity of theirs by adventurers who fought these little pests, not as a piece in the puzzle of a conspiracy by an ancient evil who styled himself as a god.
Serving as manual laborers, construction crews, miners, cooks, maids, chattel servants, carpenters, waiters, farmers, masseuses, coopers, weavers, and whatever other menial tasks the armies of Dememoras could think of, they provided many services and goods, thus freeing up more dracons to fight. The fact that Dememoras could create such a larger series of armies in secret was amazing, but it could not have been done without the aid of countless little kobolds providing the daily work needed to supply such a force. He and his forces mistreated these little humanoids, regularly abusing them, underfeeding them, keeping them as slaves, and refusing to allow them anything more than a loincloth to wear and a straw mat to sleep on. This was to be the fate of the "weak", if there was submission from them, they could live, but it would be a horribly degraded existence.
