Bleeding

Bleeding is the process by which a lightsaber crystal is rebounded with a new Force user. Both practitioners of the Light side and Dark side of the Force may practice this process, though by different means. Force users who have constructed a lightsaber engage in a special relationship with the crystal that powers their weapon. Some feel the crystal 'called' them or selected them as much as they selected the crystal, and others have described the relationship as akin to a parent imprinting on an offspring or a spouse bonding with their partner. The crystal, and my extension the lightsaber, become a part of their personal being.

Sometimes while constructing a lightsaber a Force user will use a crystal that had previously been used in another Force user's weapon. The crystal may have been inherited, gifted, or taken as a trophy. This crystal will be bonded to its previous owner, and while it may work it will not naturally bond to its new owner. This impairs the relationship between weapon and wielder, and inhibits the mastery of the weapon. The relationship between the crystal and the previous owner must be broken and a new relationship built or forced upon it.

The exact process is a carefully guarded secret among many Force sects.
