A Note on the Sentai

I wrote a little bit of history to my story yesterday, trying to get the kinks worked out. Thought I'd share it.

The inhabitants of Nova Sentai were a race of traders and explorers that were one of the first to investigate wormhole technology. Eventually abandoned in favour of hyper-light travel, wormholes or darkgates as they became known, would eventually form part of the reason the Sentai have become one of the most scattered peoples in the galaxy.

In 22-24, the Arthannan opened negotiations with the Sentai in a bid to garner darkgate technology. Negotiations fell through, and soon tensions escalated towards open war, lasting several years. Darkgates were used on both sides, though the Arthannan could only utilise drives from captured vessels, and the Sentai's weaponry was sub-standard compared to their foe.

Eventually a decisive strike for the Sentai was rendered into an abject failure, ultimately culminating in defeat for the species, when their fleet tried to utilise newly found Hyper-Light technology for the first time. Many of the ships were destroyed upon stardrive use, others were disabled on re-entry, right next to the Arthannan fleet. The flagship, however, fared both better and worse. Their prototype drive landing them within striking distance of the Arthannan home world, the Sentai opened a barrage of darkgate missiles upon their foe. The missiles malfunctioned, opening up a rift in space and hurtling hundreds of undetonated warheads along with the ship through to an unknown destination.

The Sentai home world soon faced the wrath of the Arthannan fleet. Unprotected and at their wits end, they took to the stars, abandoning the planet and its civilisation to the Arthannan. Harried though they were, they still managed to escape, eventually settling amongst other peoples, integrating but never forgetting their roots through the ages. 

The Arthannan eventually obtained their darkgate technology, but as the Sentai had found to their detriment, it was unstable and ineffective at best. In a cataclysm borne of hubris and greed, the Arthannan homeworld was torn asunder, rendered into a million asteroids, soon sucked into orbit around their sun. The off-worlders of that time were left adrift, having to find their own way in the galaxy as the Sentai had done, forming colonies and raiding the stars in an impotent rage at the foes that had escaped them.

Through the ages Sentai and Arthannan fought, their grudges settling into grim hatred. And to a few, the lost flagship began to take on a kind of mythical quality. A treasure hunt in the depths of space, a race between two enemies for a glowing prize and one final, solid victory.
