Arrays were lines of controlled and concentrated aether, but most of them would work better if there was a concentration of a particular element.
For example, the arrays in the System walls were mostly made of Earth elements. If she were to somehow recreate the array (which she was still far from doing) using the 'unfiltered' aether all around her, the effect would've been less because it was 'impure'.
This was something she and the team had theorized after months of staring at her notes.
If the theory was correct, then this skill could mean a step forward in that direction.
That was something from the far future, of course. She hadn't even been able to use the skill for its intended purpose yet.
No, she hadn't even learned of it.
For now, Althea continued to read on, memorizing everything. Even with her eidetic memory, she was still required to reread things over and over to be able to truly familiarize herself with the content.
