Pillar of Fire
this was one of two rune-covered obelisks that were presented to apprentices of the Sith academy on Korriban, during the decades leading up to the Great Sith War, as part of their final test. After defeating several terentatek beasts, the apprentices found themselves in a chamber with the The Pillar of Fire, which stood opposite the Pillar of Ice. Sith apprentices had to choose one to help them cross a pool of acid in order to reach their last challenge.
