In a massive interstellar war, the fifteen major races suffered devastating losses. To ensure their survival, they all descended on the Central Planet and signed a peace treaty.
On the day the treaty was signed, the insectoid king lost his beloved son. His mental powers ran wild, and he nearly went mad, slaughtering his way across the Central Planet.
The fifteen major races and twenty minor races joined forces to seal off the Central Planet, trapping the insectoid king inside. In just ten years, both the planet and its king would be annihilated, and the insectoid royal line would cease to exist.
History would call it the Lost Crown.
The insectoids had lost their king, and their bloodthirsty, war-loving nature was no longer held in check. They became frenzied, savage, and cruel, hating every other life-form in the galaxy without distinction and bent on exterminating them all.
The First Legion guarded the Central Planet, vowing to remain with their king. The day he died would be their day of burial.
The Second Legion sowed discord among the various races and used others to do their killing. If discovered, they immediately chose to perish alongside their targets.
The Third, Fourth, and Fifth Legions waged war abroad, leaving nothing but bones in their wake.
The Sixth Legion planted spies and carried out random assassinations of the rising stars of every race.
The Seventh Legion vanished...
The Eighth and Ninth Legions slumbered in insectoid territory...
The galaxy was once again plunged into a massive war.
Premise: There will always be someone willing to risk everything for you
