"A dark land of ancient plateaus and oceans of night... Night becomes day, and our ancient fathers aid us... We erase that which blights our face, but not that which lies within... The land that rests in twilight will be the place of our greatest triumph and also our greatest shame."
In 2506, Shakuras was invaded by Amon's corrupted zerg and hybrid forces after the warp gate on Aiur was activated, following the failed Reclamation of Aiur. After evacuating as many Nerazim as possible, Matriarch Vorazun and Hierarch Artanis worked together to defend the xel'naga temple until it was overloaded, destroying the planet and a sizeable portion of Amon's forces.
Shakuras possessed at least two moons of different sizes, the larger of which has the outermost orbital path and the smaller one being much closer. Its star system also featured a gas giant.
Shakuras was a desert planet with ebony rock, fixed in a state of perpetual twilight, although there were no clear differences between night and day. In contrast with Aiur (homeworld of the Khalaiprotoss), Shakuras was a planet almost devoid of vegetation. It was also the homeworld of the kakaru. The skeletons of previously-existing lifeforms could be found scattered over the planet.
The xel'naga constructed a temple above a nexus of powerful cosmic energies. When the Dark Templar found it, they decided to remain there to study it. Shakuras was a harsh desert, and the Dark Templar had to alter their own biology to adapt to the world.
Despite their isolation, Shakuras was not entirely unknown to the Khalai, the prophet Tenarsis receiving visions of the world and the conflict that would blight it long before the reunification of the protoss kindreds.
"The destruction of our ancient home of Aiur still pains me. The blackening of our lands, the destruction of our cities and the defilement of our temples by the accursed Zerg leaves a void in my soul that can never again be filled. Now Shakuras is my new home, and I am finally beginning to understand why our exiled Dark Templar brethren settled here. I've spent many days just quietly gazing out at the strangely sad beauty of the water here. The waves hold the color of pure indigo and they mesmerize me and calm my soul. How could anyone leave this place after seeing such sights?"
Kerrigan offered to help find the Uraj and Khalis. She then departed with Artanis, Zeratul, the Executor and a protoss army to secure the crystals.
In their absence, Aldaris and a legion of Khalai survivors began an open revolt against Raszagal. Upon the army's return, Raszagal ordered the Executor to terminate Aldaris and quell the uprising. Artanis and Zeratul confronted Aldaris, but Kerrigan killed him before he could reveal that she had manipulated Raszagal. Zeratul banished Kerrigan from Shakuras for interfering in a protoss matter.
Artanis carried the Uraj to the temple while Zeratul handled the Khalis. The zerg sent all their legions to destroy them, but the Executor prevented the zerg from destroying the temple while Artanis and Zeratul channeled the temple's energies. Once the channeling was complete, the protoss withdrew into the temple. The resulting explosion obliterated the zerg on Shakuras but left a wasteland of sand dunes and shattered ruins.
Ulrezaj had hatched another plot, however. Working with terran mercenary commander Alan Schezar, they created an EMP Generator capable of weakening protoss psionic energy, granting an enormous combat advantage. However, Zeratul's forces were able to defeat Ulrezaj and save their planet.
When Kerrigan returned to Shakuras, the pylon clusters generated an electromagnetic field that prevented her fliers from maneuvering. These clusters were infiltrated by Samir Duran, who caused a surge within them, resulting in an explosion which destroyed Talematros. During the confusion, Kerrigan's minions kidnapped Raszagal.
After retreating from Char Aleph, Artanis and the survivors of his fleet returned to Shakuras to rebuild their civilization. For the next four years, the Khalai attempted to reunify their society with the Dark Templar. Interacting with them and the temple led to many new developments as the protoss prepared themselves for continuing the war with the zerg.
"Shakuras has fallen! The warp gate linking this world to Aiur has been reopened. Countless hybrid and zerg pour from the other side! They've obliterated our cities. Decimated our Shadow Guard. We are trying to evacuate the remaining population, but I am uncertain whether we can hold long enough to get them safely away."
During the End War, Shakuras was overrun by zerg and hybrid forces that poured onto the world via its warp gate, coming from Aiur. The Shadow Guard was decimated and its cities obliterated. By the time the Spear of Adun arrived, only Talematros remained in Nerazim hands, and even then, control was tenuous. Daelaam forces under the command of Hierarch Artanis cleared out the city's launch bays, allowing the remaining Nerazim to be evacuated.
Although managing a successful evacuation of the Nerazim from Shakuras was made, Vorazun didn't want to leave Shakuras in Amon's hands as had Aiur. She reluctantly decided to rather destroy the whole planet and instead aid Artanis in his quest to finally retake Aiur, stating that "our home has always been Aiur". Artanis protested at first, particularly given Shakuras sheltered the Khalai during the Brood War, but in the end also made a bold plan to bleed Amon, by Shakuras only after a large number of Zerg and Amon's hybrids were present on it's surface.
"Shakuras is gone. It has become one with the eternal night. But the traditions we forged there will remain with us forever."
- Matriarch Vorazun on the passing of Shakuras(src)
In order to destroy the planet, the protoss overloaded the planet's xel'naga temple, and lured as many of the zerg and hybrids onto the planet as possible. The protoss once again defended the xel'naga temple from the zerg until its overload could be activated. Over a billion of Amon's corrupted zerg forces were killed in this process, along with many of Amon's hybrids.

Shakuras was planned to appear in StarCraft: Ghost, specifically the idea of an underground area in which Dark Templar resided. The idea never got off the ground however.
↑Raszagal: "Congratulations, Executor. Your success has brought us the promise of hope against the Zerg. However, we face a new threat within our own ranks. In your absence, JudicatorAldaris and an entire legion of Khalai survivors from Aiur have begun an open revolt against us." Zeratul: "By the gods, this is ill news indeed! Why would Aldaris betray us so?" Raszagal: "He and his ilk believe that it was wrong to have abandoned Aiur and consorted with our people. Their prejudices have driven them to perpetuate the Conclave's sins against us! Even now, Aldaris and his loyalist templar forces are preparing to attack our Citadel." Artanis: "I can scarcely believe this. As if the Zerg were not enough! Matriarch, are you certain of this?" Raszagal: "All too certain, young templar. Executor, as Matriarch of the Dark Templar and custodian of this world, I hereby order you to terminate Judicator Aldaris, and quell this untimely uprising without delay! There will be no dissent among us while the Zerg are poised to strike!" StarCraft: Brood War. Vivendi Games. Level/area: The Insurgent (in English). 1998.
↑Aldaris: "You can no longer afford to be so naive, Artanis. While you were securing the crystals, I discovered that your Matriarch has been harboring a dark secret! She has been manipulated by de-" Sarah Kerrigan: "We have no time for this!" Zeratul: "Kerrigan... What have you done?" Kerrigan: "I just cleaned up your mess, Protoss. Don't be so squeamish." Zeratul: "Wretched creature! This was a Protoss matter; you had no right to interfere! Begone from this world! You are no longer welcome among us!" Kerrigan: "Fine. I've done what I came here to do. I've insured the destruction of the renegade Cerebrates, and I used you to do it. Have fun, mighty Protoss... We'll be seeing each other again, real soon..." StarCraft: Brood War. Vivendi Games.
