((Just finished the campaign as Tau. Awesome.))
Having dealt with most of Gorgutz's personal squad, Ores'Ka prepared to track down and eliminate the rest of the orks. Unlike most commanders, he was quite capable of wiping out the enemy alone using his stealth field. The Dark Crusade had also given the chance to study Eldar technologies to great detail, allowing the creation of the Portal Matrix. With the ability to instantly switch between a vast array of weapons and other wargear, Ores'Ka could customize his battlesuit in the midst of battle to suit the need of the moment, vastly increasing his combat capability.

However, Ores'Ka wasn't the only Tau weapon that had been sent to the planet. The entire Tau research facility based on Kronos had been hit by a warp storm. Somehow, the vile energies of the Warp had thrown them into what seemed to be an unknown sector of space, where Ores'Ka had found the barbarian Orcs. He had no idea how Gorgutz had ended up here, but he had no doubt that the Orc Warlord posed a threat to everything on the planet, esspecially if there were large numbers of local orcs to be roused into a Waaagh.

In a completely different area, several Earth Caste scientists were working together with a group of drones. The research facility had been heavily damaged by the Warp Storm, and most of the Fire Warriors guarding the facility had perished in the brief battles against the nearly infinite hordes of Demons in the Warp. The facility was broken down and practically defenseless, and worst of all, filled with experimental weaponry using Necron energies, attempts to further improve Tau firepower and integrate the capabilities of other races into their military.
