"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]

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]

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 d
