Anunnaki

One bad egg. That's all it took to almost destroy a species. The bad egg should have been discarded. Anunnaki mothers know when they lay a bad egg and its left to die naturally. This one is taken by a barren female. Desperate for motherhood. It hatches and that hatchling becomes a monster. Eight Anunnaki clans rise to dominance on Anun by conquering their rivals turning them into slaves or a food source. They would probably have destroyed themselves if it were not for the intervention from an unlikely otherworldly source. Help comes at a price. The Anunnaki don't even know they are paying. This is the story of the Anunnaki. How they became the feared intergalactic powerhouse that conquered and ruled almost half of the Spiral Arm.
