The winds of change swept through Frostwood as Grey embarked on the journey to wield Astrum. Seated in the secluded training grounds, I explained the intricacies of Astrum to him.
"Astrum is unlike conventional magic, Grey," I began. "It grants control over fundamental aspects of existence: time, space, life, death, creation, and destruction. But here's the catch – one can only master one aspect."
Grey's eyes widened with curiosity. "But why not two aspects? Wouldn't that make someone more powerful?"
I smiled, appreciating his inquisitiveness. "To wield a single aspect, you must intimately understand its characteristics and workings. It's about mastery. For instance, my command over time came only when I delved deep into its essence."
Respect and admiration shone in Grey's eyes, but what I said next left him astounded.
"But you, Grey, are different," I continued. "Your talent lies in the space aspect, yet you possess an understanding of my time art. With proper comprehension of both, and maybe even other aspects, you could hope to wield all of them. Not as potent in each as someone who masters just one, but versatile and powerful in their combination."
Grey's astonishment mirrored the realization of his unique potential. The winds whispered through Frostwood, carrying the weight of newfound possibilities and the challenge that lay ahead. The path to mastering Astrum, with its manifold aspects, stretched out before Grey, a realm of mysteries waiting to be unveiled.
