Humanus Federation

Overview
The Humanus Federation was a pre-Dominion panhuman polity, believed to be the dominant power in known space for at least an epoch. Being formed sometime after the Lost Era- much of the Federation's history is lost to time and the scraps that remain tend to paint conflicting and confusing accounts, which drives numerous conspiracy theories.

What little is verified points to the Federation being a corrupt federal democracy, akin to a "tyranny of the majority". It was very likely trans-universal, but unlikely to be trans-multiversal. Analysis of various ruins along with simple interpolation suggests a technological level of 10, commonly shared by humans before the various singularities of the Dominion, though there are several outliers which are the origin of theories that the Federation had technology unknown to the Dominion.

Theories

 * Humanus had superior technology to the Dominion in multiple fields, including possibly undiscovered ones: Backed up by a handful of physical evidence and dubious historical accounts that point to unverifiable technology. Consensus is that these are exaggerated outliers and/or fabricated.
 * Humanus had access to altphysics unknown to us: It is possible that Humanus were further along in research to alternate fields such as psionics than the Dominion due to their age and possible access to information from the Lost Era, but there is no evidence to support this.
 * Humanus were far more massive in scope than agreed and possibly trans-real: Not supported by evidence or simulations.
 * Humanus were destroyed by conflict with unknown entities: There is evidence to support this but accounts point to their collapse being more likely self-inflicted.
 * Humanus didn't dissolve and either left, 'ascended' or met an unknown fate: Baseless.
 * Humanus partook in a conflict with *various* cosmic scale stakes and collapsed after enduring a pyrrhic victory: A popular theory but even more unlikely than them being destroyed by a normal war.
