Form II Ilum Diatium Lightsaber was a blue lightsaber which General Kento Marek used. It used a Custom Form II LS Model, with an Ilum or Adegan crystal, and as all lightsabers do, a Diatium power cell. It was created by Kento Marek upon the finishing of his youngling training. This lightsaber was blue, as the crystal came from Ilum. It does not show much speed, but seems that it's strong point is it's power.
