The seremindir were a species endemic to the planet of Nethere. Knowledge of their culture and even physiology is limited and inherently biased through the lens of the modern Netherian cultures that had exposure to them, which in turn have been accused of a mass propaganda and censorship campaign to conceal not only the seremindir's existence from the common people, but their genocide as well.
Implications of seremindir nativity
It has been suggested that the medrin are, in fact, a subspecies of another Kin from the rest of the Ealdremen System, most commonly kronakkos. To this end, it's theorized that knowledge of the seremindir was hidden away so that the medrin would view themselves as Nethere's sole species and "owners". No adequate reasoning has been provided to support why this sort of conspiracy would begin in the first place, however, and so others suggest that in Nethere's past, the medrin warred with the seremindir and nearly wiped them out, choosing to purge their enemy from history and continue to exterminate throughout the years later until they were truly gone. Proponents of this theory are often challenged to present a reasoning for this kind of ongoing war and extinction, as well as support how there could have ever been such a widespread war with no records of it in any Netherian nation.
It is presumed that the nation of Terdeu has genetic samples from Rotus, the last known living seremindir, who died while in Terdeu's captivity. Representatives of the Veriol Alliance have requested such samples for analysis to determine if medrin and seremindir share any genetic ancestry, however distant it may be; if they naturally evolved to inhabit the same planet, then it would follow that there would be evidence of a common ancestor. Were this the case, then the medrin would have credence to their claims of nativity to Nethere. These requests most often go ignored, and, as of 4364 CGC, no one, except perhaps an unknown number of medrin working for various Netherian governments, have laid eyes on seremindir genetic sequences.
