The Icarii Campaign represents the Galactic Empire's attempt at subjugating the indigenous Icarii population residing on the planet Vestar. This military operation was spearheaded by the Lightning Battalion, reporting to General Nim and Colonel Abal Karda. Following several months characterized by intense and brutal combat, and after observing the Icarii's strange capacity to survive even after dismemberment, the Lightning Battalion resorted to utilizing a devastating biological weapon with the intention of completely wiping out the Icarii. Selestrine was the lone survivor of her kind, her head saved and stored within a kneebhide container; this container was then pilfered by Karda as he escaped Vestar.
