This Besalisk Jedi is all about getting results and, indeed, his battlefield record lists many key victories in the Clone Wars. He has an unshakable confidence in his methods, and he will brook no insubordination among his charges. In personal combat, he can be ferocious -- his giant arms carry two double-ended lightsabers, making him extremely dangerous in close quarters. Pong Krell's reputation as a successful general is well known but so is the fact that the casualty rates of the clone troopers under his command are the highest.
Umbara, known as the "Shadow World" due to the rays of its sun never completely reaching its surface, is perpetually dark. The native wildlife have adapted to survive in such gloom, making the planet perpetually dangerous. Umbara was once part of the Galactic Republic, represented in the Senate by Senator Mee Deechi. Later in the Clone Wars, the planet's loyalty wavered and the natives of Umbara allied themselves with the Separatists, bringing their extremely advanced technology to the Separatist Alliance.
During the Republic campaign to secure Umbara, the natives of the shadowy world unleashed all manner of previously unseen advanced technology against the clone trooper forces. The Umbaran MHC -- mobile heavy cannon -- is a titanic juggernaut built atop six powerful, ground-shaking legs. The dome-shaped body of the spider-like tank is heavily armored, able to withstand anti-armor infantry rockets. Mounted atop the dome on an articulated arm is a powerful electromagnetic plasma cannon. The monstrous MHC has almost no weaknesses.
Also known as an Impeding Assault Tank (IAT), the Umbaran crawler tank is a horrifying mechanical monster created by the advanced technology of the Umbaran people. The crawler tank is armed with blaster cannons, shield generators, and designed to have multiple redundancies to cope for heavy damage.
The Shadow People of Umbara have excelled in the science of technology despite their isolation from the rest of the galaxy. In their pocket of territory within the Ghost Nebula, they have engineered potent examples of energy weaponry and anti-gravity systems with performance that exceeds galactic standards. One impressive example is the Umbaran hover tank. The single-pilot vehicle is built around an armored control pod bracketed by twin conducting vanes that each house an electromagnetic plasma cannon that can decimate entire platoons of enemy troops with a single blast. When the tank is powered down, in docked configuration, the conducting vanes rotate and split open to serve as landing struts.
Using the highly advanced technology native to its planet of development, the Umbaran starfighter is the most intuitively-designed ship in the galaxy. Its shielded cockpit surrounded the pilot with touch-sensitive holographic displays that react instantly to touch. The ship's unique construction allows its airframe to flex and bend, not only adding to its maneuverability, but allowing it to land and take off with a minimal of mechanical effort. It boasts the energetic plasma weapons found on many Umbaran craft, as well as modular missile pods.
