Shadow Slave

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.

Insidious, shapeless, everchanging. What was he supposed to do with that?

But now, he understood. The key to it all was so simple and evident that he almost laughed. Why had he not guessed earlier? It was so obvious.

The idea that tied everything together was as innate to the nature of shadows as formlessness and elusiveness.

It was imitation.

After all, what were the first two things that came to mind when one thought about shadows? That they lived in the dark and imitated the things that hid them from light.

The foundation of the shadow style was indeed insidious, shapeless, and everchanging. Its core concept was to steal that which made the enemy strong and use it to destroy them.

To master that style, he had to learn how to behave like a shadow.

Sunny stared at Nephis and Caster, but didn't see them. His mind was consumed completely by the sudden revelation. He had no time to pay attention to their fight anymore.

This style… this style had endless potential. If he managed to master it, he would be able to counter any style or technique used against him, not to mention become an immensely unpredictable opponent.

What could be more unpredictable than a formless shadow?

Of course, it was easier said than done. To begin with, while the ability to imitate the enemy was incredibly powerful, it also demanded an incredible amount of talent, experience, and insight from the user. You couldn't imitate that which you didn't understand, after all.

More importantly, this was just the foundation of the style. He still had to expand it into the actual collection of specific principles... and retrain himself accordingly.

That was a mammoth task.
