The reason was pretty simple. Compared to the summoning type of magic, the attaching magic type was more suitable for the magic core. Take Anna's Blackfire as an instance. Even if the magic core had the exact same cyclone, it could not release or withdraw the power as freely as Anna. However, for the attaching magic type, they only needed to inject magic power into it to activate the instrument.
Mystery Moon had the ability to convert magnetic force into various types of energy, which would largely benefit Neverwinter.
Dawn I had always been a rare energy resource. Even with the help of Doris, it barely sufficed the need. With the expansion of the industry, they would soon run out of power.
