Great Magic

The ability to create, cast, or develop anything with simple willpower or desire alone, rather than utilizing mana as a catalyst. Through many trials and tribulations, only a handful of individuals of humanity have ever taken a glimpse of what knowledge lies beyond the Well of the Aether. Wielders who bear the burden of this authority, are granted the capability to change or alter the laws of the universe themselves, whether temporarily or permanently.
Great Magic is the origin of what modern magic attempts to mimic.
This extraordinary power was prevalent during the Age of Divinity. In that era, the divines wielded these abilities to create the very laws and rules that presently govern the universe. With unparalleled mastery over this great magic, the divines shaped reality to their desires, establishing fundamental principles that define the nature of existence and common sense today.
While the divines held access to these formidable powers, such awe-inspiring feats are rarely seen. The consequences of unleashing this great magic universally were deemed too perilous. The established rules and laws, meticulously crafted during the Age of Divinity, formed the bedrock of the world's existence. Disrupting these foundations on a global scale risked unraveling the very fabric of reality, leading to unpredictable and catastrophic consequences for the entire world. None have borne witness to its manifestation since the age following the decline of the divines. However, its existence cannot be outright denied, lingering as an irresistible allure, a relic of a bygone era in which many yearn to obtain.
