Sectaurs: Warriors of Symbion #1

The planet Symbion is the site of a failed genetic experiment that caused insects and arachnids grow to frightening proportions and the inhabitants to take on insectoid characteristics.

Prince Dargon, ruler of the peaceful Shining Realm of Prosperon, and his allies are in conflict with the forces of Empress Devora, ruler of the Dark Domain of Synax, and her henchmen. The two factions rival each other for possession of the Hyves, fortresses of an ancient civilization holding the key to ultimate power.
