During a civil war, a faction of the Croke introduced the invasive Lugubraa species in the Croke Reach to fight as soldiers for them. Over the following 300 years, however, the Lugubraa began to overrun Croke settlements, including Explume Minor, causing the Croke to fight for their survival. They eventually commissioned the cloners of the extra-galactic planet Kamino to create a genetically engineered variant of the Lugubraa. The purpose behind the creation of the Lugubraa variant was to help fight the Lugubraa in the Croke Reach, but, over time, the engineered members of that species proved to be a threat to the Croke, as well.
