Just as Heizen entered the Silvermoon Grotto, he heard the thunder followed by intense shaking. Even though he had run into a separate space, he wasn't spared, as the entire cave showed signs of collapsing.
Fortunately, he wasn't at the center of the spell, and he was already far enough when he entered the Silvermoon Grotto. After a brief shaking, the cave returned to its natural peacefulness, showing no apparent damage.
'Fortunately, I wasn't stupid,' Heizen thought, feeling relieved.
At first, he had thought of hiding inside the Silvermoon Grotto immediately after throwing the scroll. Since it was an Epic artifact with a separate space, maybe it could remain steady.
However, he changed his mind at the last minute and chose to run. If he hadn't done that, the Silvermoon Grotto might have been destroyed, and they would likely have been severely injured.
"Are you alright?" Luna asked with concern as she approached him.
