The universe we know (stars, laws, civilization) is just an "epochal bubble" floating in the "infinite ruins". Guixu is the end and starting point of all things, capable of swallowing and assimilating everything. At the end of each era, the "tide of return to ruins" will rise, annihilating the current universe, leaving only the core fragments of laws, which will become the foundation of the next era. Our story begins at the end of the ninth era - the "Era of All Laws".
