After the universe had expanded for eons and after the birth and death of uncountable galaxies, the last star burned dim. A creature stirred in this black void of space at the end of time, curling tightly around the star–taking the last vestiges of energy as its own.
The death of a universe was a tragic thing to the creature, but it had to sustain itself and did not want to die. It had toyed with the notion of killing itself, but starvation was a hard way to go. Inevitably, once it got too hungry, it would gorge on some planet teeming with life. The being always thought it was a shame that billions or trillions of diverse life forms had to die, but they were too hungry for that to make a real difference.
As soon as the being absorbed the last vestiges of energy from the dying star, it ripped a tear into a new dimension using all the energy it had stored over billions of years. A singularity’s explosion made room for the entity as it moved into the new universe. Mourning the death of its past habitat, the creature promised itself that it would savor this one and try to make it last a little longer.
As galaxies formed, and star systems settled into predictable orbits, the creature lounged in a solar nebula, bathing in the cosmic energy of creation. Thinking about how to do things differently, it began to entertain wilder ideas as the millennia passed. Slowly, a strange option came into focus for the creature, the way mortal beings achieved their semblance of immortality- through offspring–was more sustainable. Perhaps, the entity mused, by creating smaller versions of itself, they might disperse their gathering of energy to such a minuscule rate that it could be done sustainably. Maybe this way, this universe would be able to last longer than the one before.
As the plan was mulled over and pondered for the hundreds of years following, eventually, the creature broke off half of its energy, reshaped it into eight beings, and assigned each of them a portion of the universe to harvest. Each new being dispersed into its respective parts of the dimension. Once there, they repeated the same process and created more creatures enough to have one per galaxy under their dominion. Each of these galaxy-offspring divided themselves to make one for each star system in their galaxies. Then those star-system creatures split in half to create enough beings for each planet in their systems. Finally, the last fission took place as each planet entity separated half of themselves into enough beings to live in the plethora of environments on each planet and coax life into existence.
Once the ecosystems started to thrive, the creature instructed their offspring to protect those environments, feed on the ambient energy and eventually, bring the excess back to the beast in the next order above them until finally, the original Godbeast could be fed.
