Kasshralhyot

"Be nothing."

- Rin Sakaros

Kasshralhyot was the most severe, and correspondingly rarest, sentence that could be passed on a citizen of the Golden Empire. It could be ordered only by the Sovereign, and as of 140 ABY, it had been dealt out only once, on the treasonous Consul Vessyk in 127 ABY. Due to the intense demands of some of its component actions, it could only be performed by an atypically powerful Force user.

Incensed beyond all bearing at the actions of Vessyk, exploiting the people of Ekshi who Queen Rin Sakaros had entrusted to his care and justifying it with the authority she had given him, Rin journeyed to Ekshi in person to deal justice to him. After easily defeating him in a lightsaber duel, she vented her wrath on him in the following way:
 * Cut off both his hands at the wrists and legs at the knees
 * Cut through his eyes to blind him
 * Electrocuted him with Force lightning
 * Cut him off from the Force
 * Used the Force to completely his mind
 * Beheaded him
 * Had his corpse burned to ashes
 * Packed the ashes into a hyperspace-capable delivery system and launched them into Ekshi's sun
 * Deleted every mention of him in all the historical archives of the Empire and forbade anyone to ever speak his name again

Asked by her brother Tariun why she had chosen such a complex and ruthless form of execution, Rin responded that, "Even if there is life in the Force after this one is done, he will not know it."

Rin named the punishment Kasshralhyot, borrowing a word from the Peoly, a particularly violent and militant species she had been forced to destroy; it meant "complete and utter annihilation in every conceivable way". As Rin expected, fear of this new and terrifying penalty swept through the ranks of the Consuls, ensuring that the very few who might be tempted to betray her in the first place would likely be too frightened of the consequences to go through with it.

Behind the scenes
The final element of Kasshralhyot, deletion of all records of a person's existence, is based on the Roman damnato memoriae.
