Benjamin carefully observed the three runes.
Actually, starting from a very long time ago, he had always been curious about the nature of these magical runes. From the process of their creation, the continuous accumulation of the water elemental energy, and finally forming runes under the stimulation of spells— this seemed to indicate that runes were some special polymer of elemental energy.
However, from these three runes, Benjamin could not feel any signs of the accumulation of water elemental energy.
It did not seem like the product of anything arranged in a special way, but rather a naturally formed ensemble. There was no structure on the inside, so it was not dissectible, and even more so it could not be seen what material it was made out of. It... was just itself.
Faced with such magical runes, Benjamin felt really troubled.
