Deliora was one of the demons created by the legendary "Black Wizard," Zeref.
It was an immortal calamity demon that had wreaked havoc long ago, causing countless deaths. It could destroy an entire massive city in less than a day, and it had also destroyed the city where Gray's family lived, indirectly killing both of his parents.

"Yay!"
"Happy, we're about to get rich!"
"Mm-hmm!"
"Happy's going to buy lots and lots of fish! Happy's going to live in a little house covered in fish!"

Regardless, the S-Class Mission to save Galuna Island had indeed been basically completed. That was an indisputable fact! Now that Deliora and the people who had tried to revive it had all been defeated, the moonlight-collecting ritual had finally ended, and everyone had returned to the villagers' settlement, the only thing left for them
