XBox@IGN has put up a brand new preview of Korriban in KOTOR II. As it's only comprised of 2 paragraphs, here it is in full:
<blockquotE>Korriban is a graveyard world that has died twice -- once when it served as the burial grounds of the ancient lords of the Sith, and again, when the end of the Jedi Civil War brought death to Korriban. There are half-whispered rumors and speculations of what took place on Korriban after Malak's defeat -- some claim that the remaining Sith Lords fought amongst themselves for control, while others claim that the Republic itself attacked Korriban and destroyed the Sith Academy on its surface. Whatever the case, there are few in the Republic willing to speak of it, and there are no Sith remaining to ask what transpired there.

All that remain on Korriban's surface are beasts and echoes, ghosts of the dead that still walk and whisper the ancient teachings of the Sith. To touch down within its windswept canyons and blood-red skies is to be filled with a sense of unease - then a slow dread, as the evil of Korriban begins to take hold. There are also tales of dark side beasts, the Hssiss, that now stalk its surface, and even more sinister dangers lurking within hidden tombs within the Valley of the Sith Lords.[/indent]
I guess it's true about what they say: there is no rest for the wicked.

Thanks for the heads up, Kumquatq3.
