From SkyeWalkers: A Clone Wars Story:
“I feel pretty kriffing Class-D’ed myself,” Halagad said between huffs and spits of dross.
Class-D disintegration … otherwise known as transcendental annihilation. The invention of “absolute” disruptor technology, by the mysterious fatalists of Plootark IX, introduced a form of pure death so unique in heinousness the alien science had been outlawed the galaxy-over. Believed to target midi-chlorians, matter thus atomically eradicated was said to disappear even from detection in the Force—the ultimate affront to life.
In the everlasting words of Frank Booth, “Fuck that shit!”
