Kurnorioss, loosely translated into Gothic as "Hunter of the Void" but more commonly referred to as the Voidhunters, is a unique group of Aeldari. Many Craftworlds and Corsair fleets maintain close ties based on the homeworld of the Corsairs' leadership and/or crew but the Voidhunters take it one step further and are both Corsairs and Craftworlders. More specifically they are Asuryani first and Anrathe second. The Voidhunters are an ancient Wild Rider clan from Saim-Hann whose youth, rather than undergoing the typical journeys amongst their Exodite brethren that many others from Saim-Hann make, undertake their coming of age trials by joining their clan's Corsair forces and raiding the galaxy for a time. Their time among the stars informs the forces they bring to bear in Saim-Hann's defense. Many become accomplished Skyreavers or Starfang pilots & gunners as Corsairs and continue to fight similarly after returning to the Craftworld, becoming Vyper operators or joining a Swooping Hawk shrine. Some however, never return and elect to remain among the outcast portion of the clan.
Much like their unique nature, the fleet's structure is similarly distinct from other Corsairs. The Clan Chieftain occupies the position and role normally reserved for a Prince/Princess, commanding the fleet's Baron's much as they are first among the leaders of their clan's various kinbands. While the fleet does occasionally accept Exodite newcomers from Maiden Worlds they interact with, this happens more rarely than in other fleets and they never accept Drukhari runaways. This further reinforces the culture and keeps it distinct from other Corsairs. They also maintain a slightly distinct aesthetic from the standard Saim-Hann visuals, as many clans do. In the Voidhunters' case they emphasize black and white with red acting as more of an accent. Their soulstones tend to take on orange and purple hues.
Additionally as their Aeldari name may suggest, there exists a connection to the former god, Kurnous. While Saim-Hann as a whole relates to the Cosmic Serpent, the Voidhunters also identify with the Faolchú (the Great Falcon), Kurnous's messenger. This connection can also be seen in the number of Swooping Hawks and Skyreavers amongst their ranks, in addition to their preference for transporting smaller groups of infantry via Falcon grav-tanks over the larger Wave Serpent. The clan chieftain wields a blade named Angauriel (Falling Doom), said to be forged from a feather of the Great Hawk just as Eldanesh's blade Anaris was from the Great Falcon. They honor Khaine as all Asuryani do but beyond their Swooping Hawk warriors and a handful of Shining Spears their only other Aspect Warriors of note are Crimson Hunters, for their connection to the Hunter. They maintain two shrines; the Shrine of Falling Stars for the Swooping Hawks and the Crimson Hunter Shrine of the Soaring Strike. Due to most clan warriors having piloted craft at some point in their career as a Corsair or for the Craftworld, many of the clan's wraith's empower hemlock wraithfighters. Certain aspects of the clan's history is referenced in their kin-rune.
One of the Voidhunters main quests is to locate as many of the crystal relics known as the Eyes of Kurnous as possible. Much like the Ynnari's belief that collecting all the croneswords will allow for the god of death's creation, Voidhunter Farseers maintain tradition of a prophecy that the recombined eyes of the hunter god will create a relic so powerful in sight, that it will empower a future Farseer to perfectly predict the path to an Aeldari victory at Rhana Dandra. It is rumoured that they possess more shards of Kurnous's eyes than any other Aeldari. They respect the Ynnari for their devotion to a similar path but remain more aloof in their support than the rest of Craftworld Saim-Hann.
Like most Corsair fleets they have developed rivals over the years. In the Voidhunters' case their main rival is fellow Corsair fleet the Void Reapers, a fleet of primarily Drukhari origin that preys on other Aeldari as readily as they do other species. The two fleets have clashed on multiple occasions, as the Void Reapers, who were formerly a cabal of some standing in Commorragh seek primarily to obtain enough slaves and technology from their Exodite and Craftworld cousins to regain their position in the Dark City. In contrast to a deep disdain for their Dark Kin, the Voidhunters maintain close ties with the Harlequins, particularly those of the Masque of Shrouded Sight, whose purpose is to locate and preserve Aeldari relics. Combined Voidhunter and Harlequin forces will often accompany each other to Crone Worlds in search of such treasures.
