Reality

The People of Old in Krea didn't use the word "reality" in the way we do– as a simple descriptor of what's "real." Instead, Reality, with a capital "R," is a proper noun, a concept almost as grand and ancient as the universe itself. It's not a deity in the traditional sense, lacking a physical form or a yearning for worship. Instead, think of it as the code that dictates the universe's operation. It's the grand architect laying down the laws of cause and effect, the very foundation upon which everything exists.
Within this framework, Reality prioritizes certain aspects over others. Every pebble on the path, every fluttering leaf, exists in a state dictated by its hand. Importance plays a crucial role. Reality guards fundamental laws more fiercely than ephemeral details. The fundamental laws, gravity keeping you grounded, the memories people have in their head, are deeply ingrained and resistant to manipulation. Wielding the Words of Power, however, offers a chance to bend these rules, albeit with varying degrees of difficulty. Persuading Reality to alter the course of a raging river might be easier than convincing it to defy gravity altogether.
Words of Power are not mere incantations, but utterances that resonate with the very essence of Reality. Spoken with the right intent and understanding, they can bend the established rules, manipulate causes and effects, or even alter the state of being for an object or creature. It's not a walk in the park, though. Reality doesn't take kindly to tampering with its current coding. It might push back, test the user's will, or make the manipulation incredibly difficult. But if the user persists, and the Words of Power are strong enough, Reality will eventually relent. Once the alteration is woven in, it becomes part of the fabric– unless, of course, someone uses opposing Words of Power to revert or change it further. Reality on its own, however, can't rewrite its own rules.
The beauty of Words of Power lies in their accessibility. Unlike magic systems that require immense reserves of energy or years of honed skill, all you need is the knowledge itself. The correct sequence of words, spoken with the right intent and understanding, can resonate with the fabric of Reality and enact change. This democratizes power in a way, making it available to anyone with the capacity to learn and pronounce the ancient tongue. However, the potential consequences of wielding such power should never be underestimated.

Limitations

The Scope of Reality remains a profound mystery. It encompasses the entirety of the known universe, stretching back into an unknown past. Did it always exist? Was it created by something grander? These questions remain unanswered. The People of Old, despite their reverence, wouldn't call it a god. It lacks the whims and desires of a deity. Reality is an impartial force, responding to the whispers of power with blind indifference. However, while Reality doesn't play favorites, some individuals possess a natural affinity for specific aspects of Reality.
However, while Words of Power appear limitless in their potential, there are a handful of fundamental concepts that even Reality struggles to manipulate. One such concept is the very essence of Death. While a skilled wielder might weave Words of Power to bring someone back from the brink, the result is rarely a perfect replica. The revived individual might resemble their former self and retain their memories, but a crucial spark, the essence of their being, might be forever lost. What returns is a mere echo, a haunting mimicry of the life that once was.
Another unshakeable aspect lies within Reality itself. The People of Old, despite their vast knowledge, never discovered the true name of Reality. It's the ultimate code, the fundamental script from which the universe is built. Words of Power can rewrite the rules within this code, manipulate the variables, but they cannot alter the coder themself. You can change the way the game is played, but you cannot change the game itself.
The final frontier lies in the creation of something from absolute nothingness. While Reality can effortlessly transform one material into another, it seems to balk at the concept of true creation. If a user attempts to conjure a magnificent gem from thin air, Reality might instead subtly manipulate the environment, perhaps pulling the necessary components from a hidden crevice or a distant mountain. The user might perceive this as creation, but it's ultimately a clever sleight of hand, a manipulation of existing materials rather than the generation of something entirely new.
