Eternal Entropy Change

"Any sufficiently advanced technology is indistinguishable from magic." "The essence of the universe is nothing more than a flow of consciousness, information, and energy." "Matter is energy bound up." "On a cosmic scale, there is no difference between an individual and a civilization." "The increase in entropy is irreversible, and the food chain is still the law." "'Four legs' are walking, we are mice hiding in the rules." Tavern Keeper, Chameleon, Yama... There are individuals hibernating, seeking survival. Humans, Boltzmanns, quadrupeds... There are ethnic groups growing and traveling. Science fiction + fantasy, no system, unlimited flow, traditional novel, single female protagonist
