A hundred thousand years of knowledge gathered by a dying sentient sphere and passed to the USS Discovery in 2257, which Control sought in order to become fully conscious and which later grew into Zora.
In the Discovery episode An Obol for Charon, the ship is held by a vast and ancient living sphere. Saru realises that it is dying and wants only to hand on what it has learned. Discovery receives the whole archive, a record of 100,000 years of galactic history.
The rogue Section 31 intelligence Control needs that data to achieve full awareness, which would lead to the end of all organic life. The archive defends itself, blocking attempts to delete it or to destroy the ship, so in Such Sweet Sorrow Michael Burnham leads Discovery 930 years into the future to put it out of reach.
In the 32nd century the data merges with the ship's computer and develops a personality. It comforts the crew in Forget Me Not and takes the name Zora, the same intelligence seen in the Short Trek Calypso.
