So, long, long ago, on a planet in the Milky Way, dwells the Qualian civilization. The time is around Earth’s 16th century, in the Tasadian Empire. Emperor Zora II has just been betrayed and nearly assassinated by the famous High General Duluk. Duluk now waits underneath the great prison, waiting to receive his, most likely, brutal torture and punishment. Probably the eye melter or head cruising methods. But when he talks to Zora, he tells him he’s getting a different punishment.
The next day, Zora’s guards are seen chasing Duluk out of the city, and he is never seen or heard from by anybody ever again. He’s alive, and is about to take a permanent vacation in the Hageorian Desert, but he's still alive. But Zora goes on to make a purge of all memories of Duluk. Files such as Duluks certificate of hatching, his college files, and etc. Paintings of Duluk are painted over, and every single scroll or stone carving mentioning the name Duluk is edited.
People are discouraged from mentioning Duluk, and since hatchlings are raised en masse in government controlled facilities, Duluks legacy is deleted, while he is technically still alive. Duluk, after about 50 years, is a hazy urban legend like figure that no one is sure even existed.
In Qualian culture, I plan for this punishment, called deletion, to be feared worse than any other by Qualiabs. But my question is, why would this, seemingly mild punishment, be so especially feared by Qualians?
