Korriban was a planet where old people went to die. It was known as "Floooorrrrriiiiiddddaaahh" by the Wookiees. Many Sith died here after they became too old to fight and were simply abandoned by their companions, who did not have time to care for the
ancient elderly. The Jedi were known to have taken craps in the unused tomb of Darth Vader.
Lord Qordis wanted to have a place to train the Sith, so he founded an academy where powerful women went to lean the art of beating their men.
The planet was never destroyed by Sith and Plunkists alike because it featured a premiere shopping center in the galaxy: Darth Mall 2, a sister mall to Darth Mall on Coruscant. The shopping center was the best in catering to Sith and was the most accessible and traversed by this group apart from the Death Star Mall and Food Court.
Destruction of the Planet
Korriban was later bombed by some idiot who hit a the big button labeled "BOMB PLANET" on his cruiser.
Darth Azula was told to find an ancient lightsaber in the ruins of Korriban. Upon arrival, she was shot at, but she didn't see anyone nearby. It turned out to be a ghost, who was angered that Darth Azula was digging up their crap. After finding the lightsaber, Azula fled from the ghosts shooting at her and left Korriban with the weapon.
