Erza originally thought she could finally reunite with Herag, it's been so lonely all these years.
However, when she was ready to find Herag, she learned that he had already entered the Elf Plane.
The Doris Kingdom is too far from here, and news takes time to travel.
At that time, Erza was furious and then wrote this letter to send over, so that when Herag returns, he can see it and won't go back to the Land of Dawn right after.
Over the years, Erza actually kept an eye on Herag's news, even knowing many things about him in the Land of Dawn.
Seeing Herag become stronger step by step, going farther and farther, Erza was sincerely happy from the heart.
After Herag learned all this from the letter, ripples arose in his heart.
Wherever you are, knowing that someone cares about you feels different.
From the letter, Herag also learned that Erza had become a Level 1 Official Wizard and is currently at the Gaseous Stage.
