Ikjuttar

The Ikjuttar are a secretive and isolationist Covenant fringe culture seemingly confined to the Xiale system, located in the far trailing-side reaches of the Orion Arm. According to their transmissions to the Covenant's emissaries as of circa 1890 CE, the Ikjuttar had devoted all of their resources as a civilization to a slow-burn war of attrition against a localized hegemonizing swarm of indeterminate nature and origin. Interestingly, they seem to lack a slipspace travel capability, yet have access to a high level of technology likely of Forerunner origin, and their home system appears to be heavily fortified with exotic defenses that entirely stymied the Covenant's attempts at invasion: any ships that crossed inside the local cometary cloud appeared to disappear entirely.

Because of the seeming impossibility of even entering the Xiale system, combined with the potentially volatile nature of the Ikjuttar's single-minded mission, the Covenant left them to their own devices, while simultaneously keeping watch on them in case the object of their containment efforts were to spill over from their meager sphere of influence. As such, knowledge on the Ikjuttar is patchy at best. No one knows what they look like, and their society and culture can only be guessed at from the rather curt transmissions they sent to the Covenant. The Ikjuttar have no presence outside their home system, and only communicate remotely. The Covenant leadership largely suppressed knowledge of their existence, lest their authority in the Covenant's sole primacy over Forerunner technology be potentially undermined, and they are generally seen more as an obscure myth than an actual civilization. Formally speaking, the Covenant has been in a constant state of war with the Ikjuttar for about seven centuries, and their conversion, when brought up, was regarded as being "ongoing".
