Devastation of Aust

"Prepare to unleash our weapons of mass destruction"

- Supreme Warlord Le'ok giving the order to utilize biological and chemical weaponry against Aust

The Devastation of Aust was the opening battle of the Lefan Crusade. It was fought in 4,000 BBY between the newly born Lefan Imperium and the primitive natives of Aust. After the Lefan forces who landed met hostile enemies, they withdrew and the three Gastan-class bioships orbiting the planet unleashed weapons of mass destruction on the planet, rendering it uninhabitable for two millenia.

Prelude
The Lefan Imperium was founded in 4,000 BBY by the final union of the three major tribes of Lef. They wished to continue their warlike and offensive policy in space, with their primary goal being the conquest of the Xoret Cluster. After building up their navy, consisting of enormous bioships, an Imperium task force was sent to the planet of Auts, which had been charted by scientists a decade before.

The battle
"Very well, Supreme Warlord. Do as you wish."

- Emperor Kay'lef authorizing the Supreme Warlord to devastate the planet.

The Lefan ships arrived above the planet, and the one carrying ground forces descended to the surface of the oceanic world. The primitive natives attacked them with slugthrowers, which barely caused damage, but convinced Supreme Warlord Le'ok that a preemptive strike was necessary to show the strength of the Imperium. After the Emperor of Lef gave his permission to Le'ok's plan, the bioships retreated to orbit and unleashed a variety of deadly chemical and biological weapons on the unsuspecting world. The results were just as frightening as the Lefans planned; the oceans dried up and a firestrom swept across Aust, killing every living thing on Aust. It would take two millenia for the planet to recuperate.
