Star Wars; Diminished Hope
Ziost (pronounced /ziɒst/)3 was once a world made up entirely of an ancient dark forest. However, the trees withered away and the planet became very similar (in landscape) to Korriban. Much of the planet was covered in ice. Not only was it a focal point of the dark side, but it was also the adopted homeworld and Imperial capital of the Sith species, who left their original homeworld, Korriban as a graveyard world after the death of their leader Adas.
