Lambent
this unusual form of plantlife was bio-engineered by the Yuuzhan Vong as a source of light-producing crystals. These crystals were used in a variety of ways, from personal light-sources to the running lights of a worldship. The lambent itself was formed from a base of green, knife-like leaves sprouting from the ground. Growing from the base were three or four stalks, atop which sat hairy, bloodred flowers. The flowers were the size of a human fist, and protected the growing crystal. A Yuuzhan Vong was required to rub and stroke the petals of the flower until they opened, a process which attuned the alien to the flower. Once the petals opened, a yellow bulb could be cut from the plant and hulled, revealing the light-giving, silicon crystal. The crystals could be "turned on" by a Yuuzhan Vong which was attuned to the crystal, and the amount of light it gave off could be regulated by mental contact with the crystal. Like all Yuuzhan Vong constructs, the lambent crystal was alive, transpiring whenever gases were available. Anakin Solo discovered that the lambent crystal he used to replace the stone in his lightsaber gave him a tenuous connection to the Yuuzhan Vong through the Force, but was unable to get more than a sense of presence. Nonetheless, it helped him recognize the presence of Yuuzhan Vong in a given area. After the Second Battle of Coruscant, the remnants of the New Republic fed false information to the Yuuzahn Vong, claiming that they were trying to grow lambents at the recaptured base on Borleias. The information claimed that the Jedi Knights had been planning to use lambent crystals in the lightsabers, to better attune themselves to the alien invaders.
