Because of the chaotic flow of mana in and out of the artificial wonder, it doesn't look like a lung to Arthur. It looks more like an organelle within a cell or even an entire single-celled organism.
But the one thing it had in common with a natural wonder is the instinctive inducement of temptation with any organism that is lacking in potential once that organism gazes at it.

The fatigue that he had been feeling after working hard for so long disappeared. He became full of energy and yearning. He felt like leaping forward to grab the artificial wonder and begin the process of establishing his foundation immediately.
