Final Assault on Csilla

The Final Assault on Csilla was a battle that occurred around 4300 BBY. The assault was the climax of a great war between the Chiss Ascendancy and a merciless opponent in the Unknown Regions. The Chiss Defense Force had been pushed back to their capital planet of Csilla, and despite their numerous losses, the Chiss had a secret superweapon: the Starflash, an ancient alien energy weapon kept secret by the Stybla family. The Starflash could only be used once and required twenty individuals to operate it—guaranteeing the deaths of all twenty. Warriors of the Mitth family volunteered, willing to sacrifice their lives for the salvation of the Ascendancy.

The weapon and all twenty Mitth, known as the Starflash team, were loaded onto a heavily armed ship and sent into the center of the enemy fleet. When the fleet neared the ship, the Mitth warriors activated the weapon, shooting a massive burst of tachyonic and lightspeed energy into Csilla's sun, which triggered a return blast thousands of times more powerful back at the weapon. The ship and the enemy fleet were destroyed, rendering the Chiss victorious. However, the burst into the sun had disrupted the sun's core, causing it to cool over the next decades, freezing the planet and eventually making Csilla uninhabitable on the surface. The Mitth were elevated to the status of ruling family, and Mitth Patriarch Mitth'omo'ross, core name "Thomoro," was granted the Stybla honorific "-odo," adopting the name "Mitth'omo'rossodo." Additionally, she was given the epithet "The Tragic" for her sons' sacrfice.
