Yprin Yprikushma

Yprin Yprikushma was the Political and Morale Commander of all human forces during the human-Forerunner wars.

Biography
Yprikushma and her science team originally discovered the ancient being known as the Primordial buried within a desolate planet at the edges of the galaxy. She recognized the entity's scientific potential and brought it to Charum Hakkor in a stasis capsule for study and questioning. According to Yprikushma, the information gained from the Primordial saved billions of human lives in the human-Flood war; however, her sworn opponent, Forthencho, disputed this, claiming it was the humans themselves who came up with the "solution" to the Flood and arguing that the Primordial caused the downfall of humanity's civilization by gravely demoralizing them.

Yprikushma also traced humanity's origins to Erde-Tyrene, a source of much dispute to the ancient humans, as humanity had lost most of their records during a technological dark age in their ancient past. Others, such as Forthencho, believed humanity's origins to be elsewhere, having witnessed ruins built by humans on many other worlds. Regardless of the opposition, Yprikushma's discovery of humanity's true homeworld gained her the lofty status she held during the war with the Forerunners. In addition, it was her idea to analyze Forerunner technology and tactics gained from humanity's early conflicts with the Forerunners - technology that bought humanity decades of time against the numerically overwhelming and technologically superior Forerunner military.

During the final battle of Charum Hakkor, she commanded a special force group of 7,000 warriors and 70 ships, tasked with defending the Charum Hakkor arena, the site of the Primordial's timelock and where the remaining human survivors had gathered. The overwhelming final assault led by the Didact himself eventually broke through Charum Hakkor's defenses and humanity's remaining forces were forced to surrender. Despite knowing her impending execution, she had hoped to warn the Forerunners about the Flood in order to ensure the safety for the rest of the galaxy.

Though Yprikushma was executed shortly afterward, her consciousness was extracted by the Composer and archived by the Librarian. Nearly nine thousand years later, the Librarian imprinted Yprikushma's archived personality into the genetic material of a Florian known as Riser as part of a geas. Some time after awakening within Riser, she "reunited" with Forthencho, whose personality was in turn carried by another human, Chakas.
