Arrays were built on runes, that was the main rule of all arrays. Flags also could be added. Also arrays work by taking certain places and form star shapes to be activated.
However from what Arthur saw, the diagram worked by hand seals. The originals made a big circle with one in the center to activate the diagram.
Each made a seal with their hands before he saw a gush of purple energy emanated from their bodies. "So they use the diagrams to control the purple energy… That's interesting," Arthur muttered.
In his mind he started to take some notes regarding this. He was sure the seal used now were just the tip of the iceberg. And he was very interested in knowing everything.
He wanted to get a good grasp over this so he could control the energy inside the ores. If the problem of the berserk energy was solved, then he could easily melt down the ores and reform them as he liked.
