Precursors

The Sol Primeval (also known as the Precursors), are a Vex collective spanning from the distant past of the Vex network, reported to have been first encountered in the Vault of Glass. They can be identified by their silver-white frames and angular headgear.

Origins
The exact origins of the Sol Primeval are not known. However it is often believed they came from the ancient past. The Primeval are responsible for the creation of the Undying Mind, an ancient Axis Mind of the Sol Divisive feared by fellow Vex. They would eventually come to inhabit the Simulant Past in the Infinite Forest on Mercury, the Glass Throne in the Vault of Glass and Echo Chamber on Venus. The algorithm that was used to generate the infinite forest would be located in the Gardener's Spire in the Simulant Past and overseen by Dendron, Root Mind.

Fall of the Vault of Glass
Members of the division would later be confronted in the Glass Throne by a six man fireteam led by the Guardian. They would fail to defend the Vault and Atheon, Time's Conflux would be destroyed.

Destruction of the Undying Mind
When the Undying Mind attempted to seal the Black Garden in Darkness once more and recreate the Black Heart, the Vanguard would send a fireteam to stop this. The Precursors would enter the Garden in an attempt to assist their dark creation, despite their efforts they failed and the Undying Mind was destroyed.

Curse of Osiris
Later on Mercury, The Guardian and Sagira entered the Simulant Past to download the forest's algorithm at the Gardener's Spire before the Vex created the Infinite Forest. They would destroy Dendron, Root Mind and begin downloading the algorithm. However the Axis Mind of the Infinite Forest Panoptes arrived, captured Sagira's consciousness and banished the Guardian out of the forest. However the Guardian would succeed, destroying Panoptes, Infinite Mind, and Osiris would regain Sagira. Later the legendary Warlock would ask for the assistance of a fireteam after he recreated and lost control of Dendron, Root Mind.

Season of the Witch
The Guardian and Eris Morn would encounter and defeat Precursor units in the Court of Savathûn led by the three Ternary Minds.

Structure
According to Ghost analysis, the Precursors had their casings built long before the age of humanity. The assumption is these Vex are the ancestors of those faced today, but due to the flexible nature of the Vex timeline the truth may not be so simple.

Following the death of Dominus Ghaul, they began to gather on Mercury at the Infinite Forest alongside the Descendants, in order to unite under Panoptes, Infinite Mind. These Vex units are largely encountered in the Simulant Past which shows the Vex arriving on Mercury and beginning their conversion of the planet.

Trivia

 * In Destiny, regular Precursors appear as Majors.
 * In the description of The Undying Mind, it is hinted that Precursors created the Axis Mind. This is supported by the Strike of the same name, as you fight Precursors on your mission to destroy the Mind, thus destroying its protectors.
