That was the voice he recognized, the voice of the unknown man who had appeared in his visions on several occasions in the past. It had been there when he comprehended the symbol inside the golden box of the secret sword chamber in the Forgeheart Kingdom and again when he completed the forging of the unnamed divine sword.
This unknown man felt inexplicably close to him, and it wouldn't be an exaggeration to say Aldrian considered that man like blood family.
Aldrian was immersed in a state of comprehension as he pondered the thread of origin. That voice kept repeating itself, like some kind of recording playing inside his mind. His thoughts spun with the emotions he experienced when he saw the visions of himself and Sylphia, all while hearing the voice over and over again. At one point, he felt as if he could leap into one of the visions and enter that world, but he held himself back.
