For anything to exist, there had to be building blocks that supported that existence.
For a building to be formed, blocks were required to form it.
What of the blocks? Well, a single block was formed by adding several materials in order to attain the shape, size, and quality that was desired.
And what of those materials? They also required various elements and compounds in order to be formed.
In essence, all that existed required building blocks. Initially, it started with simple and physical elements, but the deeper one went into the components, the more the revelations of the invisible, undetectable, began to unravel itself.
However, no matter the building blocks or Concepts, Aquarius never had a problem with any of them. In fact, she could freely detect, reach, and influence all of them.
She could interfere with areas that would be considered the limit for even the most powerful entities.
