N. Jemisin: The Obelisk Gate

Madness Season:3 Before Imperial–7 Imperial. Proximate cause: volcanic eruption. Location: Kiash Traps. The eruption of multiple vents of an ancient supervolcano (the same one responsible for the Twin Season of approximately 10,000 years previous) launched large deposits of the dark-colored mineral augite into the air. The resulting ten years of darkness was not only devastating in the usual Seasonal way, but resulted in a higher than usual incidence of mental illness. The Sanzed Equatorial Affiliation (commonly called the Sanze Empire) was born in this Season as Warlord Verishe of Yumenes conquered multiple ailing comms using psychological warfare techniques. (See The Art of Madness , various authors, Sixth University Press.) Verishe named herself Emperor on the day the first sunlight returned.

[Editor’s note:Much of the information about Seasons prior to the founding of Sanze is contradictory or unconfirmed. The following are Seasons agreed upon by the Seventh University Archaeomestric Conference of 2532.]

Wandering Season:Approximately 800 Before Imperial. Proximate cause: magnetic pole shift. Location: unverifiable. This Season resulted in the extinction of several important trade crops of the time, and twenty years of famine resulting from pollinators confused by the movement of true north.

Season of Changed Wind:Approximately 1900 Before Imperial. Proximate cause: unknown. Location: unverifiable. For reasons unknown, the direction of the prevailing winds shifted for many years before returning to normal. Consensus agrees that this was a Season, despite the lack of atmospheric occlusion, because only a substantial (and likely far-oceanic) seismic event could have triggered it.

Heavy Metal Season:Approximately 4200 Before Imperial. Proximate cause: volcanic eruption. Location: Somidlats near Eastern Coastals. A volcanic eruption (believed to be Mount Yrga) caused atmospheric occlusion for ten years, exacerbated by widespread mercury contamination throughout the eastern half of the Stillness.

Season of Yellow Seas:Approximately 9200 Before Imperial. Proximate cause: unknown. Location: Eastern and Western Coastals, and coastal regions as far south as the Antarctics. This Season is only known through written accounts found in Equatorial ruins. For unknown reasons, a widespread bacterial bloom toxified nearly all sea life and caused coastal famines for several decades.

Twin Season:Approximately 9800 Before Imperial. Proximate cause: volcanic eruption. Location: Somidlats. Per songs and oral histories dating from the time, the eruption of one volcanic vent caused a three-year occlusion. As this began to clear, it was followed by a second eruption of a different vent, which extended the occlusion by thirty more years.

Antarctics:The southernmost latitudes of the continent. Also refers to people from antarctic-region comms.

Arctics:The northernmost latitudes of the continent. Also refers to people from arctic-region comms.

Ashblow Hair:A distinctive Sanzed racial trait, deemed in the current guidelines of the Breeder use-caste to be advantageous and therefore given preference in selection. Ashblow hair is notably coarse and thick, generally growing in an upward flare; at length, it falls around the face and shoulders. It is acid-resistant and retains little water after immersion, and has been proven effective as an ash filter in extreme circumstances. In most comms, Breeder guidelines acknowledge texture alone; however, Equatorial Breeders generally also require natural “ash” coloration (slate gray to white, present from birth) for the coveted designation.

Bastard:A person born without a use-caste, which is only possible for boys whose fathers are unknown. Those who distinguish themselves may be permitted to bear their mother’s use-caste at comm-naming.

Blow:A volcano. Also called firemountains in some Coastal languages.

Boil:A geyser, hot spring, or steam vent.

Breeder:One of the seven common use-castes. Breeders are individuals selected for their health and desirable conformation. During a Season, they are responsible for the maintenance of healthy bloodlines and the improvement of comm or race by selective measures. Breeders born into the caste who do not meet acceptable community standards may be permitted to bear the use-caste of a close relative at comm-naming.

Cache:Stored food and supplies. Comms maintain guarded, locked storecaches at all times against the possibility of a Fifth Season. Only recognized comm members are entitled to a share of the cache, though adults may use their share to feed unrecognized children and others. Individual households often maintain their own housecaches, equally guarded against non–family members.

Cebaki:A member of the Cebaki race. Cebak was once a nation (unit of a deprecated political system, Before Imperial) in the Somidlats, though it was reorganized into the quartent system when the Old Sanze Empire conquered it centuries ago.

Coaster:A person from a coastal comm. Few coastal comms can afford to hire Imperial Orogenes to raise reefs or otherwise protect against tsunami, so coastal cities must perpetually rebuild and tend to be resource-poor as a result. People from the western coast of the continent tend to be pale, straight-haired, and sometimes have eyes with epicanthic folds. People from the eastern coast tend to be dark, kinky-haired, and sometimes have eyes with epicanthic folds.

Comm:Community. The smallest sociopolitical unit of the Imperial governance system, generally corresponding to one city or town, although very large cities may contain several comms. Accepted members of a comm are those who have been accorded rights of cache-share and protection, and who in turn support the comm through taxes or other contributions.

Commless:Criminals and other undesirables unable to gain acceptance in any comm.

Comm Name:The third name borne by most citizens, indicating their comm allegiance and rights. This name is generally bestowed at puberty as a coming-of-age, indicating that a person has been deemed a valuable member of the community. Immigrants to a comm may request adoption into that comm; upon acceptance, they take on the adoptive comm’s name as their own.

Creche:A place where children too young to work are cared for while adults carry out needed tasks for the comm. When circumstances permit, a place of learning.

Equatorials:Latitudes surrounding and including the equator, excepting coastal regions. Also refers to people from equatorial-region comms. Thanks to temperate weather and relative stability at the center of the continental plate, Equatorial comms tend to be prosperous and politically powerful. The Equatorials once formed the core of the Old Sanze Empire.

Fault:A place where breaks in the earth make frequent, severe shakes and blows more likely.

Fifth Season:An extended winter—lasting at least six months, per Imperial designation—triggered by seismic activity or other large-scale environmental alteration.

Fulcrum:A paramilitary order created by Old Sanze after the Season of Teeth (1560 Imperial). The headquarters of the Fulcrum is in Yumenes, although two satellite Fulcrums are located in the Arctic and Antarctic regions, for maximum continental coverage. Fulcrum-trained orogenes (or “Imperial Orogenes”) are legally permitted to practice the otherwise-illegal craft of orogeny, under strict organizational rules and with the close supervision of the Guardian order. The Fulcrum is self-managed and self-sufficient. Imperial Orogenes are marked by their black uniforms, and colloquially known as “blackjackets.”
