In Heir to the Stars, the term Human is an acronym for (Hierarchy Unevolved Morphology A-bap-ical New-men-on). It is a constant that remains the same with the only exception being in Solecism’s (Past Arc). Human means the same for everyone labeled as one (unless it is referring to a specific dimension in which humans are identified). There are regular humans, metahumans, transcendent humans, and higher dimensional humans.
Humans are the expression of the lowest concept in Heir to the Stars. That doesn’t mean that humans are always the weakest characters, but that their origin and inherent qualities provide them the least benefit more often than not.
Because humans came about due to the inverse touch of Chaos, humans are in fact a foreign being to the Universe and that the resulting paradoxical nature of the human mind and spirit is responsible for humanity’s incapability to gradually progress its society in accord with nature. However, it is because of this paradoxical principle, that humans are able to use expressions of Heir to the Stars.
The inherent power of a human in and of itself is very little; however, humans have the ability to learn to manipulate and take advantage of various forces like science, religion, law, magic and so on in order to boost themselves. While the human physiology of other works typically uses the field of physics as the basis for their abilities, Heir to the Stars humans use any of an abstract chain of different fields.
In Heir to the Stars, humans are empowered by various things other than physical, spritual and mental exercise, and other ways of physically perfecting the body, generally by realizing the logic of Heir to the Stars.

Ultimately though, humanity within Heir to the Stars can express various feats from annihilating an entire infinite metaverse, to stopping metaversal metaphysical annihilation without effort, to reacting to infinite speed or even breaking through logic barriers.
Being human is for better or worse, the lowest pinnacle of being, but depending on your strength of will or logic, you can rise to be better than the Tier you stand on.
