d20 Future: CODEX GALACTICA
On 3,000BG the Aleeriens become a powerful spacefaring race with great advances in cybernetics and computers. They call themselves the Aleerin Empire and the seat of their empire was their home planet Aleer. A thousand years later the the Aleerin join forces with the N’sss Colonies to organize the salves races against the Elohim Empire and win their freedom in a single great coordinated multiplanet battle.
The Aleerin also did war against the Sathar Hegemony and on 1702AG at the beginning of the Third Galactic War the Medurr Empire tries to invade the Thuldan Empire and all planets suffered for this attack. The N’sss retracted to their original system and avoided conflict, limiting their actions to only defending themselves.
The Aleerin Empire then created the [Etoile] as cybernetic weapons and the Etoile malfunctioned and try to destroy them leaving the Aleerin with no choice than to destroy the Etoile. To create the Etoile the Aleerin used cybernetic technology combined with prohibited Elohim Empire elemental technology (technology that was believed was also contaminated by the Void).
After that failure, the aleerin modified humans and other races using extensive cybernetics, upgrading them for the war effort as super-soldiers. The remained soldiers became the members of the Cult of the Cykotek.
After the Third Galactic War the Aleerin have lost many colonies and a mayor part of their fleet no to mention most of their cyborg army. The Aleerin dropped the Empire from their name and started an era of peace and technological advantages.
