Purifier

"You would do well to remember, we will outlive you. And we do not forget."

- A purifier to a Templar

The purifiers are an ancient robotic race created by the protoss.

Origins
The purifiers were built under direct order of the Conclave to be an ultimate fighting force at a time when protoss scientists were making technological advancements in intelligent robotics and artificial intelligence. The program was originally kept in shadow and unified by the belief that consciousness could be turned into data, thereby used to preserve the thought-process and decision-making ability of a formerly living being. Studies proved that the replications were often 99.3% accurate to the protoss subject the replication was patterned after. The Conclave moved to use this technology to build a force replicated from the greatest warriors in history.

They did not, however, treat the purifiers with the same respect afforded to regular Templar. Instead, the purifiers were little more than slaves in the Conclave's eyes. Eventually, the purifiers chose to rebel, killing their masters. In return, the Conclave determined that the purifiers were too dangerous and banned them. They were powered down and launched away in a command vessel, Cybros, to be reactivated only in the direst of circumstances.

Reactivation
During the war between Amon and the Protoss Protectorate, Hierarch Artanis came to Cybros to reactivate them, though also had to deal with the presence of the zerg. After activating the Purifiers in Cybros, the Purifiers set to purify Endion through Cybros's weaponry, purging it due to massive zerg infestation. They then agreed to fight for the Protoss Protectorate after given reassurance by Hierarch Artanis that they will be treated as equals, as long as the Purifier with Talandar's consciousness became their representative. They were present during the Daelaam's second attempt to reclaim Aiur, alongside the Tal'Darim. Cybros, the Tal'Darim fleet and the Spear of Adun rained heavy weapon support and destroyed Amon's physical body. After the reclamation, they became a part of the unified protoss, alongside the Khalai and the Nerazim.
