"The frigid ice world of Ilum was one of the most sacred locatoins of Jedi power in the Republic. Nearly every Jedi made a pilgrimage there at least once during their training to receive visions in the Force-rich caves and construct a first lightsaber. The Jedi temple there was subject to a vicious Separatist attack that might have dealt irreparable damage to the Jedi Order had it not been for the timely intervention of Padme Amidala.

Though foul weather and cold can sometimes endanger astromech droids, Artoo did not hesitate to rush to his mistress' side and warn her of an impending attack.
This uptight protocol droid, sworn to serve and protect Senator Amidala, provided a much needed distraction.
Quick-thinking and brave, Padme made a career out of snatching victory from the very jaws of defeat. On Ilum, her sharp eye and keen mind - along with a thermal detonator - saved her from an ambush by a squad of heavily armed chameleon droids.
So named because of their ability to seamlessly blend in with their surroundings, these modified probe droids launched devastating sabotage and sneak-attack missions across the galaxy. They destroyed the crystal caves on Ilum, and nearly dispatched two Jedi Knights in the process."
