LightSabres!

The Imperial equivilent of lightsabers would be some kind of Xenos / Ancient Artifact, as a small cylyndrical case.

'Lightsabers' are actually a varient of normal power weapons, but instead of projecting the energy field around a solid weapon it is projected in a variable length tube fashion eminating from the end of the hand peice. Because of this the weight of the weapon is significantly reduced, along with its potential to destroy other weapons (because it has no physical blade).

The saber also has the ability to function as a force weapon and draws a psker's energy and channels it into the center of the energy field, often creating a coloured glow in the blade. It can, naturally be used with the deflect shot ability as it is a force/power weapon, and all blades have the magic absorbion daemonic blade abiltiy because they channel psychic energies into the blade.
Also, for every psychic power dispelled by the blade in that turn, an extra D10 can be added as per force weapon boosting for that same turn only (or next if they are dispelled after the characters turn)

Stats:

All as per a Force Sword (or halberd if your going Darth Maul)except: Reach: 1 - 3 (variable length; can be drawn at any length, takes one action to change length)

Special abilities:

Magic Absorbson Force Weapon (+1D10 for each nullified power) 60% chance of destroying parried or parrying weapons

Also allows character to re-roll one failed action roll in close combat.
