Before the conclusion of the Great Hyperspace War, the world of Ambria was laid waste by the schemes of a female Sith follower. This Inner Rim planet, a place rich in ores and home to many sentient species, fell under the control of this disciple, a Sith sorceress who utilized the power of the dark side. During this period, the planet's resources were systematically drained at the command of the sorceress, who forced into servitude the native people and used the local animals as work animals. For centuries, the sorceress directed the building of a massive obelisk in the planet's north-central area.
Once the obelisk was finished, the sorceress tried to dominate Ambria completely using an intricate Sith ceremony. To achieve this, the disciple drew upon a level of dark side energy greater than anyone had ever attempted before. However, the sorceress perished when she lost control of this power, unleashing a wave of Force energy that annihilated all other life forms on the planet. Furthermore, Ambria itself suffered immense damage from the unleashed energy, twisting its terrain and saturating it with the dark side of the Force.
