At first thought, one might not believe there was much to learn from a formation that turned on the lights. Yet, from just a simple glance Ed could tell there was something different about this formation.
'The size of the array…' The runes inside the array were compact yet clearly defined, this resulted in a smaller overall size. Yet, it also looked like these compact runes held slightly more complex functions inside them in spite of this smaller size!
'The form…' There was a form to this array, but there were also offshoots that did not conform to the traditionally taught array logic. The arrays Ed learned tended to use shapes to circulate the mana/energy.
The formation before him was using direct runic lines, however. It was like a wire and while Ed did something similar, what he did was more like using a very thin runic rectangle. Not only did this require more runes, but the rune lines were also less occult.
