The Lords of Purala IV constituted a noble class linked to the world of Purala IV. At some point before 27 BBY, they contacted the cloning experts of Kamino with a request: to create Human soldiers intended for infiltration teams. The clones manufactured by the Kaminoans were intentionally designed with sterility through genetic engineering; however, these initial clone versions exhibited significantly elevated levels of mental instability, deficient unit cohesion, a lack of creative thinking and adaptability, and reduced aggression during simulated combat scenarios.
The Kaminoans tried to remedy these issues by employing synthetic hormones, modifying cortical reward pathways, and incorporating special dietary supplements, but the improvements observed were negligible across all instances. Due to the Puralan project, Senior Research Geneticist Hali Ke concluded that allowing Human clones the capacity to reproduce was the only viable method for ensuring the creation of effective and aggressive soldiers. The knowledge gained from the Puralan endeavor was then incorporated into the Kaminoans' project to develop the clone troopers for the Grand Army of the Republic.
