Fundamental-Elements

The Fundamental-Elements are the elements that compose all things, from the most singular and basic elements to the most advanced and complex combinations. All elements exist as part of natural pairs, known as the Basic-Aspect and the Evolved-Aspect.
 * The Central-Elements are the elements that form the foundation of all others: Fire, Water, Earth, Wind, Lightning, Yin, and Yang (Basic), and Flame, Liquid, Ground, Breeze, Electricity, Order, and Chaos (Evolved)
 * The Advanced-Elements are any elements from from the combination of two elements up to all seven elements. These elements manifest and/or fuse the aspects of their components in new intense or exotic manners.

Quartet-Grouping
When the Central-Elements and Advanced-Elements are classified as a conglomerated whole, specifically referred to as the Fundamental-Elements, Fire, Water, Earth, Wind, and Lightning (and their Evolved-Aspects) are referred to as the "elements" due to their defined qualities and properties, and Yin and Yang (and their Evolved-Aspects) are referred to as being "non-elemental" because while their features are generally defined and quantified, they exist more to alter, enhance, and/or modify the aspects of the elements that they are combined with.
