Xel'naga

From StarCraft Wiki

"I bring tidings of doom. The xel'naga return, the cycle nears its end, the artifacts are the key... to the end of all things."

―Zeratul delivers a warning to Jim Raynor^src

The xel'naga are a psionically-attuned, ancient, cosmic race. They were occasionally referred to as the most powerful species known in the universe.^[1] While there are vague references of the xel'naga conquering worlds and uplifting species, their most notable involvement was with the protoss and zerg.^[2] Their interest in these two species was due to the xel'naga not having ability to reproduce, and the xel'naga would use them to be reborn.^[3] Ironically their survival was severely jeopardized when the zerg turned on them.^[2]

[edit] History

[edit] The Cycle

The xel'naga were long-lived but could not reproduce. In the interest of survival they planned to create new xel'naga by uplifting two species. A pair of qualities was required and these were defined by the xel'naga as the purity of essence and the purity of form, and each uplifted species would be targeted for one of them. Over an extraordinary long period of time, the two species would naturally come together and merge. This cycle had manifested many times.^[3] The xel'naga traveled intergalactic distances in their worldships experimenting on and uplifting suitable candidates. For millennia they met only with failure.^[2]

[edit] The First Born

Main article: Protoss history

Eventually the xel'naga arrived in the Milky Way. As they explored its breadth they left numerous temples in their wake.

On the galactic fringe they discovered Aiur and a race of tribal hunters with a psionically-enhanced communal society. When coupled with excellent physical attributes the xel'naga recognized the natives as superior candidates for the purity of form and began uplifting them. The natives were the first experiments to progress beyond a feral stage. In recognition of this the xel'naga named their new scions protoss, meaning first born.^[2]

Initially the xel'naga kept their presence and assistance secret, but once the protoss were deemed ready the xel'naga revealed themselves openly.^[2] A "protoss" temple was built where the xel'naga first landed on Aiur.^[4] The xel'naga also constructed giant artificial caverns or a city beneath Aiur, and hid khaydarin crystals around the planet.^[5]

The protoss were united by their fascination with these new "gods." They called their new benfactors the Ihan-rii, the "Great Teachers", the "Makers", and the "Guardians".^[5] The Shelak Tribe grew closest to the xel'naga. The protoss progressed rapidly technologically but rifts began appearing between the trives concerning their perception of the xel'naga.^[2] At first, the xel'naga were intrigued by this ideological development, and conducted an experiment to see what effects the diverging tribes might have on khaydarin crystals. They created twin crystals, the Khalis and Uraj, from a monolithic crystal and gifted them to the Sargas and Akilae Tribe respectively. The crystals' powers and appearance diverged with their tribes.^[6]

The ideological split proved more severe than the xel'naga realized. The protoss fractured along tribal lines and caused the psionic communal link to break. The xel'naga were disappointed but realized having pushed the protoss too far too fast they were responsible. The xel'naga decided to leave this creation.^[2] The xel'naga were already done with the protoss, and needed to work on a new species.^[3]

Hundreds of xel'naga were killed in attacks by angered and confused protoss. While their fleet withdrew, the xel'naga left behind many artifacts such as the khaydarin crystals.^[2] At least one ship was also left behind.^[7]

The protoss degenerated into the Aeon of Strife. However the xel'naga's mark on the protoss endured, and their abandoned artifacts later aided the protoss to re-emerge from the chaos as a galactic power.^[2]

[edit] Broken Cycle

Main article: Zerg history

While the protoss were regressing they had all the essential qualities of the purity of form. The xel'naga set off to find a suitable companion embodying the purity of essence. They found a suitable candidate on the coreward world of Zerus. There the xel'naga began genetically manipulating the zerg, an insignificant life form of miniature insectoids. The initial experiment was a resounding success. The parasitic zerg quickly became the dominant lifeform on the planet, with other creatures being assimilated and evolved or simply eliminated. The xel'naga were shocked to discover how quickly assimilated species could be changed beyond recognition within the space of a few generations.^[2]

In the view of the xel'naga, the protoss had failed due to the independence of the individual and conflicts of ego that arose from that. To avoid the same with the zerg, the xel'naga consolidated control of the collective zerg sentience into a single entity, the Overmind. The xel'naga used a psionic link with the Overmind to monitor the zerg, but the xel'naga kept the link secret as to not reveal their presence.^[2]

However, it was not long until the Overmind realized that to continue growing the zerg would need to leave Zerus,^[2] and assimilated the behemoths,^[1] enabling its forces to travel into space. It had since detected the xel'naga worldships in orbit and these made a logical first target for new material. The first sign that the xel'naga had that something was wrong was when the Overmind severed the psychic link.^[2] The zerg launched an overwhelming attack on the worldships. The "greater whole" of the xel'naga were slain and the Overmind assimilated some of the xel'naga's knowledge as it processed thousands of xel'naga into itself. Amongst other things, the zerg learned of the protoss, the other great experiment;^[2] they would become the zerg's ultimate target for assimilation.^[8][9][10]

This action threw the xel'naga plan into turmoil.^[3]

[edit] Return of the Xel'Naga

Shortly before the Brood War, the xel'naga temple on Bhekar Ro was unearthed. The temple housed a strange "phoenix-like" creature which absorbed the essences and genetics of both protoss and zerg.^[1]

At the end of the Brood War, Zeratul stumbled upon a shocking secret on a dark moon,^[11] where he discovered a protoss/zerg hybridization project overseen by the mysterious Samir Duran, who had previously appeared as an infested terran. Duran told Zeratul that Kerrigan was not in charge of his experiment, "although her rebirth into the Zerg Swarm has sped up my progress."^[11] Duran also told him that he was "a servant of a far greater power" and "this creature is the completion of a cycle. It's role in the cosmic order was preordained when the stars were young."^[11]

Samir Duran's pronouncements on the hybrids being the "completion of a cycle"^[11] led Zeratul to seek out information on this new threat.^[12] However, he was suffering mentally for numerous reasons, such as the death of Matriarch Raszagal at his hand. Four years after his discovery, Zeratul was located by a preserver, Zamara, and her terran "host", Jake Ramsey. They restored Zeratul's mood and exchanged information. According to Zamara, Samir Duran's experiments are a "perversion", and if his attempts "unify" the species become successful, it will result in "a monstrous and powerful perversion of both protoss and zerg will be set loose upon the universe, and all that [the protoss and terran] know and cherish will fall in their wake".^[3]

Zeratul traveled to the world of Pegasus, where a xel'naga temple hatched. He followed the energy creature through a wormhole to a mysterious planet on the other side.^[3]

[edit] Wings of Liberty

On a lost world, Zeratul found evidence of a prophecy of the xel'naga's return. But the question remained if they come to save, or destroy.^[13]

Zeratul appeared on the Hyperion, command ship of Raynor's Raiders. Jim Raynor had been acquiring alien artifacts to sell to the Möbius Foundation. Zeratul told him that "the xel'naga return" and that the artifacts Raynor has acquired hold the key to the end of the cycle and the end of all things.^[14]

[edit] Legacies

"The greater whole" of the xel'naga was annihilated by the zerg.^[2] Only ruins and artifacts remained, some functional, of the ancient race in and around the Koprulu Sector.

Main article: Xel'naga temple

The xel'naga have left behind many temples. On Aiur, they built a temple to mark the spot where they first set foot upon that world.^[4]

The xel'naga left a temple on Shakuras, sitting on a nexus of cosmic energy,^[15] where their marks (such as darkening the planet and a temple capable of mass destruction) are more obvious.^[16]

Still more temples have appeared on worlds such as Nemaka,^[5] Aridas (where the powerful Argus Stone was stored)^[17] and Bhekar Ro; the latter disgorged a strange energy creature which collected protoss and zerg genetics for unknown purposes.^[1]

Valerian Mengsk, the Heir Apparent of the Terran Dominion, has expressed interest in these temples,^[5] and Dominion forces have engaged in combat in an attempt to secure such temples.^[18]

Main article: Watch tower

In addition, watch towers seemingly crafted by the xel'naga have appeared.^{[19][20][21][22]}

[edit] Ara'dor

The xel'naga used a "universal natural" code the protoss termed "ara'dor",^[5] which means "perfect ratio". Terrans call it the Golden Mean, symbolized by φ ("phi").

In mathematics and the arts, two quantities are in the golden ratio if the ratio between the sum of those quantities and the larger one is the same as the ratio between the larger one and the smaller. The golden ratio is approximately 1.6180339887. The golden ratio is related to the Fibonacci sequence and the Golden Spiral.

[edit] Braken Prophecies

There are prophecies relating to the planet Braken, a protoss world with religious significance. These prophecies claim that "he who harnesses this world will someday wield a great power, sanctified by the ancient ones".^[23]

[edit] Prophecies

Near the end of the Brood War, several characters have detected a vague threat associated with the xel'naga, associated with the completion of a "cycle", which will become more apparent in StarCraft II. Meanwhile, more artifacts (such as temples) have been unearthing themselves...^[5]

[edit] Kerrigan and Zeratul's Role

Infested Kerrigan bantered with Zeratul on Char as a prelude to combat, where Zeratul told her: "Your coming has been foretold... You are part of the culmination. But not the end of it. You shall show the way, the path that must be taken, the realigning of old truths no longer valid. Yours is not the hand, but your very existence provides necessary instruction." Kerrigan did not treat the pronouncement seriously at the time.^[24]

After her victory at Char Aleph, Infested Kerrigan was unable to shake the feeling that a great threat loomed just over the horizon.^[25]

[edit] The Xel'Naga in StarCraft II

"The Zerg Swarm came as was foretold. And the protoss, firstborn of the gods, rose to fight them. Now, the xel'naga that forged us all are returning. But do they come to save... or to destroy?"

―Zeratul on the xel'naga.^src

The xel'naga will not be a playable race in StarCraft II, as only the original three races can be played.^[26][27][28]

When Blizzard Entertainment employee Karune was asked if there would be any hybrid units in StarCraft II, he replied "we are planning to explore the mysteries surrounding the Xel'naga for the single player campaign. In the campaign you will encounter several unique units that would not otherwise be seen in multiplayer."^[29]

Chris Metzen has confirmed they will be part of the backbone of the StarCraft II trilogy.^[30]
