The members are reptilian warriors of the Draconia Empire, each representing a different terrain (land, sea, air). They are each mounted upon large beasts (such as pterosaurs and dinosaurs). Each also mentions a specific enemy nation that those forms of troops are at war with.
In the expansions following the release of the final "Draconia" card, cards representing troops of the enemy nations have been released as the Sneak Peek Participation Cards in the major expansions. Contrasting to the "Draconia" cards, they are Pendulum Monsters with Monster Effects but no Pendulum Effects.
