So Erza was puzzled as to why such an entity would sign a contract with Herag.
Moreover, she was even more perplexed that Herag's messenger could actually transport people, something unheard of.
She had heard of many powerful messengers, but none that could transport people.
Regarding the toad, Herag couldn't reveal much and just smiled, saying, "Don't be puzzled, a man as charming as I am having such a messenger is only normal."
Erza knew this was probably laden with secrets, so she didn't inquire further, instead, she gently bit Herag.
"Since that's the case, make sure to visit me often in the future. Don't be like before, disappearing for over a decade without a heart. Come directly to me, and I'll explain to the people at Dream Island," Erza said.
Herag nodded, "I'll come as often as I can."
Herag's initial reason for visiting Erza was to inform her of potential future crises and the situation with the Elf Plane as a backup plan.
