Cronal

Cronal was a male Human and former Prophet of the Dark Side, was better known by his code name Blackhole, the mysterious Director of Imperial Intelligence.

Early Life
In the time when the Galactic Empire was born on 19 BBY, Cronal was an assistant at the Jedi Archives on Coruscant who was ultimately seduced by dark side of the force.

Later movements
During the height of the Imperial Civil War, Cronal was arranged by the resurrected Palpatine to capture the traitorous Mara Jade, who had left the service of the Empire and cut herself off from the Emperor's telepathic commands after killing a clone of Luke Skywalker in 9 ABY. He managed to capture Jade and had her imprisoned, but she was eventually rescued by New Republic forces.

The New Empire (139 ABY - 162 ABY)
A century later, Cronal has returned and serves Saarai's Sith Empire. He was still reclusive, and didn't think that Saarai was powerful enough to become ruler of the Sith. Cronal kept his secret hidden and decided to see if Saarai would be strong enough to destroy the Jedi and eliminate the Galactic Federation of Free Alliances. Most of his work was carried out, but he served his intelligence to form a clone army of Sith commandos.
