The Heart Below, as a cosmic entity, was once located within the core of the planet '''[[Aurelion]]'''. Historians believe that before the '''[[Convergence]]''', it served as a foundation of '''[[Humanity|human]]''' civilization, providing the immense energy source that powered much of humanity’s technological and arcane advancement.

Although commonly referred to as a singular organism, records disagree on the Heart Below’s true nature. Some surviving records imply it is a living being, while others portray it as a force of nature that somehow exhibited signs of intelligence. Due to the destruction of most pre-Convergence archives and the inaccessibility of the remains of Aurelion itself, definitive conclusions remain impossible.

The Heart Below’s collapse in the Old Aurelian year of 2005 coincided with the abandonment of Aurelion and the emergence of the '''[[Nullstar]]'''. Whether one event caused the other is up to scholarly speculation—including debates on whether the events were related at all.

==Discovery==

The exact date and circumstances of the Heart Below’s discovery remain unknown. Historians generally agree that it was uncovered during a period of deep planetary excavation and early arcane research, centuries prior to the Convergence. Initial investigations revealed an enormous concentration of energy unlike anything previously encountered. This energy could be extracted, manipulated, and distributed through both technological and arcane means. As humanity’s understanding of this phenomenon developed, they were able to create increasingly sophisticated systems to contain the Heart and harness its powers.

By the beginning of humanity’s expansion into space, orbital habitats, manufacturing facilities, and planetary infrastructure relied upon energy ultimately derived from the Heart Below.

==Relationship With Humanity==

The Heart Below is often regarded as both the greatest achievement and the greatest folly of humanity.

For generations, the entity was treated as a resource and not a living presence. Access to its power enabled extraordinary advances in science, transportation, and arcane engineering. Many modern-day historians credit it as the reason humanity achieved a technological golden age far in advance of what should have been possible.

Relatively few individuals possessed knowledge of the Heart’s existence directly. Information about its location and nature was tightly controlled by world governments and scientific institutions. To most ordinary humans, the source of their prosperity remained unknown. Modern scholars continue to debate whether the Heart Below willingly provided its power or whether humanity had imprisoned it.

==Convergence==

As reality began to destabilize in the years leading up to the Convergence, the systems designed to contain the Heart Below began to fail. Records from this period describe widespread inconsistencies and infrastructure failures. Many researchers believe these effects may have been linked to increasing strain upon the Heart itself.

When the Convergence fully manifested in 2005, everything collapsed. The exact nature of the collapse of the Heart remains one of the greatest mysteries in modern cosmology. Various theories suggest the entity died, escaped containment, transcended into another state of existence, or was torn apart in the chaos. No evidence has emerged to conclusively support any explanation.

==Legacy==

Although the Heart Below has not been sighted in any known form, its influence continues to shape modern civilization. Many philosophical texts cite the Heart Below as a cautionary tale against the exploitation of forces that are not fully understood. Others see it as a tragic figure, a cosmic being whose existence was consumed in service to a civilization that never truly comprehended what it had uncovered.

==Theories==
Given how little is certain about the Heart Below, many theories have arisen over the years to explain it.

===The Living God Hypothesis===

This theory proposes that the Heart Below was a sentient entity, perhaps even a deity by conventional definitions. Supporters point to fragmented accounts suggesting deliberate responses to external stimuli.

''Excerpt from a keynote speech delivered at one annual Symposium on Pre-Convergence Studies by Professor Helena Marr.''

 “The central question has never been whether the Heart Below was a powerful force of nature; that much is beyond dispute. Rather, today’s debate that my colleagues and I will engage with is the discussion of whether it possessed intention. We have records describing fluctuations in output that corresponded to external events. We have logs from human operators who labeled it ‘responsive to speech’. We have reports of researchers studying it, hearing voices. Our predecessors dismissed these accounts because acknowledging them would have forced the horrifying conclusion that humanity’s greatest source of prosperity may have been truly alive. They built cities atop its prison, connected civilization to its veins, and celebrated every advance without asking whether the thing beneath wanted any part of it. If the Heart Below was sentient, then the Convergence marks the death of a god at the hands of man.”

===The Cosmic Organ Theory===

According to this model, the Heart Below was not a complete organism but rather a component of a vastly larger structure extending beyond reality. Advocates note similarities between descriptions of the Heart and certain properties observed around the Nullstar.

''Excerpt from a lecture given by Dr. Veyn Halcor of the Noct Stratum Institute of Cosmological Mechanics.''

 “The greatest mistake made by Living God proponents is assuming the Heart Below itself is a self-contained, complete organism. Imagine discovering a single cell and concluding you have found an entire organism. Imagine studying a severed finger and declaring yourself an expert on the body it once belonged to! No, what you have found is evidence of the bigger picture, not the bigger picture itself. The Heart Below exhibited properties that should not have been possible. We call it a heart because humanity found it at the center of their planet. The name reveals more about human arrogance than the object itself. I would propose that what humanity discovered was not a creature, but an organ, a component. A fragment of something larger that extends beyond what we can see. And if that larger structure still exists, then the Heart Below’s collapse may have been less akin to a death and instead much closer to amputation.”

===The Seed Theory===

A minority belief among both scholars and religious groups argues that the Heart Below eventually became the Nullstar. While mainstream cosmology rejects this conclusion, the absence of definitive evidence ensures the theory remains persistent.

''Excerpt from a controversial address delivered by Sister Ilyra on Stratos before the High Stellar Council’s Committee on Cosmological Affairs.''

 “You speak of the Heart Below and the Nullstar with a degree of separation, because the alternative frightens you. You are comfortable with replacement, with extinction, with believing that one died and the other emerged. But I implore you to look at the timeline! The Nullstar appears as the Heart Below collapses, the Great Empty spreads, and magic floods our reality. All in an instant. We did not witness a death and a birth, but a transformation! A seed does not die when it becomes a tree. Perhaps humanity never killed the Heart Below, but rather it was forced to become something greater than itself, giving us the gift of every sphere, every thread of magic stretching across the cosmos.”
