"Doisac. Doisac. Doooiisac. Doi-sac. Planet of the Brutes everybody! Coulda' named it anything, they could have! But they named it Doisac. Doisac!"
— Dimkee Hotay[5]

Doisac, designated CE-75-2113 c by the Forerunners,[6] was the third planet of the Oth Sonin system and the homeworld of the Jiralhanae. The planet possessed three natural satellites, Warial, Soirapt, and Teash.[1] It was destroyed by Cortana during the Razing of Oth Sonin on November 8, 2559.[7][8]

Overview[edit]

Astronomical features[edit]

The planet was orbited by three natural satellites; Soirapt, Warial, and Teash. The latter two[9] were industrialised and populous.[3] The orbital cycles of these moons were the basis for a loosely held religion in early Jiralhanae history.[3][10]

Environmental features[edit]

Doisac was a large planet, with a diameter of 24,930 kilometers (15,490 mi) and a crushing gravity twice that of Earth.[1][2] The environment was generally earthlike, though with significantly less water coverage; twelve continents dominated the worldwide oceans, each of which housing Jiralhanae populations of varying sizes (with the three largest populations present on Rleod, Fotg, and L'Gesh).[2] The climate was tropical with surface temperatures ranging from -15 °C to 52 °C (5 °F to 125.6 °F), with at least half of the planet's surface[11] covered in lush, dense rainforests.[3] Other regions included deserts and rocky outcroppings.[12] Volcanic activity was common, with a terrain dominated by magma and magnetism,hinting at high tectonic activity and rich magnetized iron deposits.[11] Doisac's jungles became home to Jiralhanae-constructed fortress-cities, bunker complexes, and tree-citadels.[3]

The Great Immolation, the nuclear war between Jiralhanae clans, resulted in much of Doisac being plunged into a nuclear winter. The planet was still teetering on the edge of these environmental conditions by around the time of their ascension into the Covenant in 2492.[13] Much of the surface was devastated in this conflict, resulting in the destruction of cities and plains of radioactive glass being scattered across the surface.[3] This was particularly evident on the continents Gfolos and Rheolith, which were scarred by in the war and remained quarantined and off-limits until the modern day - though this did not prevent some Jiralhanae continuing to reside there.[2] While Doisac had a very harsh environment, it was still preferred by many Jiralhanae.[14]

Ecology[edit]

Doisac once had lush jungles covering nearly half of its land mass.[11] In ancient times the Jiralhanae built their tree-citadels on a massive species of tree that would have overshadowed the tallest trees of Earth.[15][3]. Much of the ecology of Doisac had been ravaged by decades of nuclear war.[3]

Because of its harsh environmental conditions, numerous predators evolved on Doisac throughout its history, among them the initially arboreal Jiralhanae.[16] Following the Great Immolation, Jiralhanae hunting packs were threatened by large predators that stalked the outlands of ruined cities.[3] Wild game existed on the planet that was hunted by the Jiralhanae for sport and sustenance.[17] In the outlaw realms, a species of cattle were bred whose populations were controlled by a castration process called keshkra.[18] The status of its native species following the Razing of Oth Sonin is not known.

Some Jiralhanae are known to refer to liars and double-crossers as ikthas, "who slither on the ground and speak with two mouths", implying a mythological creature that may have been based on a real native species.[18]

Ancient history[edit]

Doisac was visited by the Forerunners during the Lifeworkers' Conservation Measure. The Jiralhanae were one of many sentient species indexed by the Librarian for preservation aboard Installation 00. After the Halo Array was fired, the Jiralhanae were returned to Doisac to begin rebuilding their culture.[15]

Post-Great Purification[edit]

Doisac was a very war-torn land due to constant Jiralhanae civil warfare, typically between clans. Despite their savagery, Jiralhanae proved intelligent enough to achieve spaceflight and space-faring status. However, their warlike nature inevitably led them into conflict, and eventually the various Jiralhanae master-packs fell into a massive war known as the Great Immolation. The planet became heavily damaged from the use of nuclear weapons and almost led to the extinction of the Jiralhanae.[16][19] The Great Immolation failed to stop conflict, however, as the Battle of Gbraakon took place on Doisac at some point after that.[20] With Jiralhanae society collapsed, by the time the Covenant discovered them in 2492, the species had just rediscovered radio and rocketry. In their primitive state, they were quickly defeated and absorbed into the Covenant.[21] While the Jiralhanae did initially resist the Covenant, many of the younger generation were disillusioned with fighting to defend such a devastated world, which allowed them to eagerly embrace the empire and the Covenant religion.[3]

Covenant era[edit]

After their induction to the Covenant, many Jiralhanae left Doisac to settle on Covenant colonies or live on High Charity.[14] Following Atriox's rebellion and the formation of a military alliance known as the Banished, as the Warmaster gained support across the Orion Arm, the Banished War Chief Escharum turned his attention to Doisac, hoping to reignite and accelerate the Jiralhanae's progress in all political and military arenas.[22]

During the months of the Great Schism, Doisac was presumed to be a spot for battles between the Covenant and the Sangheili.[23]

Post-war[edit]

Although most Jiralhanae returned to Doisac after the Schism and the collapse of the Covenant,[16] many also continued to inhabit the worlds the Covenant had previously given them; however, due to their lack of advanced technology and their disorganized society, they were unable to obtain resources or even food for themselves resulting in famine, and instead resorted to raids on Sangheili colonies.[24] This also led to infighting on the planet itself, without a strong leader on Doisac to stabilize the planet.[25] The infighting between Doisac's master-packs put them at a disadvantage in their ongoing conflicts against the Sangheili.[26] The Children of Oth Sonin, one of the more powerful master-packs in the wake of the war and led by Chieftain Lydus, provided security and provisions to the outlying citadels across across its star system.[27] The Voice of Maardoth was once a weak tribe by comparison and relegated to Doisac's outlands, but became a powerful and imposing military force as its leader Hekabe usurped the tribe and killed his predecessor Remarus.[27]

Due to their failure to install order on Doisac,[28] and imminent famine on in March 2558 as their supplies ran short, Lydus and his Children of Oth Sonin were willing to attempt peace negotiations with the Swords of Sanghelios mediated by the United Nations Space Command on Ealen IV, until they were interrupted by a mercenary attack. The peace negotiations were left at a standstill.[24] Secretly, the Children of Oth Sonin had also struck a deal with the Banished, using the Banished to to take out Lydus' most dangerous rivals in exchange for full access to the shipyards and land under the control of the Children of Oth Sonin.[28]

This volatile political landscape proved ideal for the Banished, a Jiralhanae splinter group who had been active in raids against the Covenant even before the empire's collapse, to take advantage of the chaos and propel their own rise to power, largely directed by Escharum.[22] Between 2553 and 2558, Banished attacks on Doisac were able to impress independent clans of the Banished's strength while eliminating rival warlords who refused to bow to Atriox.[29]

By October 2558, a mass power consolidation and cooperation had begun to take form on the planet and its moons under the Banished, leading the UNSC to consider targeted strikes to prevent this unification,[4] as Chieftains under Atriox's command spread the power and influence of the Banished across Jiralhanae colonies.[30] Atriox himself had become a symbol for the Jiralhanae on the planet to rally behind with many joining the Banished.[31] Despite this, there were Jiralhanae who rejected joining the Banished due to their hatred of the Sangheili,[32] while others, such as the clans on the moon of Warial, became increasingly wary of any alliance resembling the Covenant.[22]

Created uprising[edit]

"Look upon Doisac one last time and remember: You chose this path."
— Cortana as she prepares to destroy Doisac.[7]

Following the The Reclamation in 2558, many Jiralhanae were unwilling to give in to the new Created threat. Instead, the Banished united the various clans across the planet and its moons and fought back against the Created.[22] Cortana called on the Banished leader Atriox to submit.[33] When Atriox refused her, she responded by sending a septet of Guardians to fire beams at the planet, resulting in its total destruction.[7] With the planet's physical destruction, its shards slammed into and damaged its moons.[22]

Following the destruction, the planet's cooling husk was described to be rich in materials capable of fueling generations of reprisal.[34] Some members of the Children of Oth Sonin continued to lurk in the shadows of the system.[28]

Production notes[edit]

The destruction of Doisac, as depicted in Halo Infinite was at one point in development intended to be accomplished via the firing of a Halo ring over the planet.[35] At some point in development for unknown reasons, this was changed to Guardians.

Trivia[edit]

  • The environments and structures of Doisac that are depicted in Origins appear almost identical to the planet Kashyyyk from the Star Wars franchise.
  • The Palace of the Hierarchs on High Charity had drapery that contained the continental tracery of Doisac within a circle, to make visiting Jiralhanae, such as Tartarus, feel important.[36]
