Spawn of Tiamat

In the Dungeons and Dragons fantasy role-playing game, Spawn of Tiamat are Dragons. They are the main object in a theme recently applied to such settings as Eberron and the Forgotten Realms, in that Tiamat (Dungeons & Dragons), the evil patron goddes of chaotic evil Dragon(Dungeons & Dragons)s, is waging war against Bahamut (Dungeons & Dragons), and the mortal races. In order for her legions to be more effective, she has tweaked with the eggs of her Dragon minions to produce all manner of bizarre draconic creatures suited to special roles in the war, such as assassination, bodyguarding, elite shock trooping, aerial/aquatic support, ETC...

Spawn of Tiamat are created by all manner of experiments and rituals and such upon the eggs, come in all shapes and sizes and forms, are of varying intelligence levels, perform all manner of roles, and are basically the most varied members of Dragonkind. All however, are descended from true Dragons serving Tiamat, and are fiercely loyal to both her and their parents. Spawn of Tiamat are named according to the color they and their parent are of, followed by the word spawn, and then the type of spawn they are. The creatures are the key elements in the Monster Manual IV, and the recent War of the Dragon Queen D&D miniatures pack. Below is a list of the known types of Tiamat Spawn, and a brief description of each:

These are created in large hordes to act like Draconic Ogres, Minotaurs, Orcs, Goblins, Lizardfolk and such. To gather in groups at camps on the fringes of civilization, and occasionally raid against a town or village. They look like orc-sized humanoid black Dragons with minotaur-like horns. They are often depicted with large swords or axes.
 * Blackspawn Raider

These perform, as their name suggests, the role of ambushing people. They lurk beneath the sand of their desert homes, or on top of a rock, and then leap forward like a pouncing lion and kill victims with their horn, claws, and lightning attacks. They resemble large, wingless blue Dragons with leonine bodies. They have huge front legs for attacking, and long, muscular back legs for leaping.
 * Bluespawn Ambusher

These resemble blue draconic Rhinoceri
 * Bluespawn Stormlizard
