D.F. Overlord

A huge pillar of dragon-flesh that melts down dragons and turns them into dragon-shaped flesh-masses. Everything in the cave is made of dragon-flesh, even the cave walls. Only Biomass and the Overlord don't look like dragons. The Hive is surprisingly humane. The tiers in the hierarchy are: Biomass—food and building materials, created by Drones. Drones—mindless helpers, created by Workers. Workers—specialists, created by Queens. Queens (males are Kings)—rulers of smaller Hives, created by Empresses. Empresses (males are Emperors)—rulers of larger Hives, created by the Overlord. Overlord—creator of the Dragon-Flesh Hive, ruler of the main Hive. Seed—tiny parasite that turns a host into an Overlord, excreeted by the Overlord.
