Shapeless

Observing the motions of two shadows that followed Nephis, Sunny was finally able to understand the foundation of the elusive shadow style.

Before, he only sensed a hint of its essence. He knew that just like the shadow, the hidden battle art was insidious, shapeless, and everchanging. But this was where lay the problem: a battle style was, by definition, a structured framework of patterns and principles, a doctrine that dictated how one should act to defeat an enemy.

That doctrine was used as a foundation and expanded into a variety of specific movements to create a style.

But If something didn't have a shape and its form was constantly changing, how could it ever be stable and structured? Sunny had no idea how the concepts he felt were at the core of the shadow style could create something even remotely applicable to practice.
