I'm a huge fan of the Sword of the Stars universe by Kerberos production. And writer Arinn Dembo is pretty much the reason I like them so much.
The amount of lore written by her for the universe is simply astounding, and going in all type of details often rarely covered in a scifi work.
She's aworked in the past on such series as Homeworld and Arcanum(she wrote short stories and lore for the manual of both, and had a large hand on the manual's lore surrounding the History of Karak for the original Homeworld).

As it stands, one of the groups I enjoy the most in the setting are a subgroup of the 'Morrigi" race called the "Harpies".

Kragodai: The Screamers

The word Kragodai in the Morrigi language is a masculine passive plural: literally it means "those who are made to scream".

Morrigi warriors who were enslaved by the Siren during the Suuligi War were given this name, because their screams were a symptom of the Siren's coercion. Although her control over her victims was otherwise complete, the Morrigi warriors sent to kill members of their own species would sometimes let out piercing, terrifying shrieks before they struck a killing blow.

It is said that the cry of the Kragodai was the last desperate struggle of the still-living warrior, trapped within the icy tomb of his own skull. Unable to control his body and voluntary speech, the screams of the damned soul locked inside the enslaved shell would still sometimes ring out, savage and insane, as if to beg his mother, wife, child or comrade to run.

The damage caused by the Kragodai who attacked Morrigi worlds and fleets is beyond calculation. Millions of civilians died, and the vast majority of Travelers who stood to defend their loved ones were either killed by their former brothers or enslaved by the Siren in their turn. The apocalyptic loss of life, knowledge and infrastructure may take centuries to recover; the damage done to the Morrigi culture and way of life may never heal.

The Sisters of Victory

Traditional Morrigi society does not allow females to become Travelers, and accords little respect to women who possess traditionally masculine virtues. A "proper" Morrigi female may excel in many fields, including mathematics and sciences, architecture and industrial engineering, music and the arts...but the traditional feminine virtues, however laudable, do not include martial skill or military genius.

For this and many other reasons, the defense of Morrigi space by its female population during the Suuligi War is known as The Great Shame by traditional Morrigi. The humiliating loss of Morrigi males who became Kragodai was deeply traumatic, not least because it was poorly understood, but the militarization of Morrigi women was equally upsetting to many. Several female Tribes rose to defend the Morrigi civilization against the Screamers and the Suul'ka, building their own warships and weapons to do so. For their pains they earned the name Harpeizanae, "Snatchers", because they are said to have torn out the hearts of their own husbands and sons.

The leader of the Harpy fleets during the Suuligi War was Penthesilea Alaia, "Penthesilea the Blind". When the Suul'ka attacks ceased, she and her sisters were exiled permanently from Morrigi space. Tried for Harmatia ("blasphemy") and murder, they were convicted and banished by Atreus the Bloody in the year 15,930.
The names of the Sisters of Victory were thereafter struck from public records, public speech and public memory. Their fight for the survival of their race, rather than being celebrated as heroic, was remembered only by downcast eyes and shamed silence.

Nonetheless, somewhere among the stars the Harpies are still flying, their ships painted with defiant colors and blazoned with the mocking badges of the woman warrior.
