Editing Shadowsun (section)

==Origin==
Even as a young Fire Caste warrior, O'Shaserra showed great promise as a military leader in the academies of the Tau Empire. Eventually she, as well as two Tau named [[Farsight|Shoh]] and [[Shas'o Kais|Kais]] ([[Warhammer_40,000:_Fire_Warrior|yes, ]][[Dawn_Of_War:_Dark_Crusade#Dark_Crusade|that Kais]]), were among those selected after a meteoric rise through the ranks to study under the esteemed [[Commander Puretide]], a legendary leader and tactical genius celebrated everywhere in the Tau Empire. With him, the three of them trained together in competitive and aggressive combat and tactics, and quickly proved themselves as Puretide's top three students. As such, they were made force commanders upon completing their training. Together with O'Shovah, who would eventually become known throughout the Tau Empire as Commander Farsight, O'Shaserra played a key role in the defense of the Dal'yth sept world during the [[Damocles Crusade]], during which Farsight's daring counterattacks against the invading [[Imperium|Imperial]] forces gained him much attention and esteem. However, many of them would likely have failed if not for O'Shaserra's patient efforts to coax the humans into opportune positions for Farsight's aggression.

When the old and incontinent Commander Puretide eventually died, an effort was mounted by the Ethereals to preserve his strategic brilliance for the sake of posterity. As part of this effort, they decreed that O'Shaserra, along with her fellow star Puretide disciples, would be put into a cycle of cryogenic stasis, with one awake and two asleep at all times, so that each of them could continue to serve the [[Greater Good]] far into the future. It was decided that Farsight would be the first to remain active, and O'Shaserra and Kais dutifully began their artificial slumber, trusting their comrade to do both their mentor and the Empire proud in their absence. However, Shadowsun was awakened almost two centuries later only to find that Farsight had given the Tau Empire a huge middle finger and become the leader of a group of renegade colonies on the Empire's fringe, space which was now designated as the Forbidden Zone. (See [[Farsight|Farsight's]] article for details and his side of the story.) Moreover, the Fire Caste was now divided over the issues of Farsight's motives and loyalty, with some still supporting him and others denouncing him.
