To say Arthur felt no hatred would be a lie. If anyone was put through such a nightmare, they would resent whoever did to death. Arthur was no exception, and he was certainly more head-strong when it came back to paying his debts due.
Instinctively, he used the Release rune making his body disappear from Dimon's view. When the mage saw this, he almost pissed his pants but Arthur has already appeared in front of him.
"Damn you, begone! I summon thee, Elusive Dragon!" Dimon shouted through gritted teeth as madness overtook his eyes. It was then that Arthur felt the egg, with an unstable lifeforce until now, suddenly move behind his back.
The reason Arthur didn't give regard to it because he could feel how weak its lifeforce was. The mana that has been in the cave and the dungeon was the result of so many people dying here as they suffered. However, Arthur also took notice that the egg was hungrily absorbing the mana.
