This was Link's 18th day at the crack.
Nothing else happened these days, perhaps because the powerful barrier kept the enemies away or perhaps because Link's fight against the divine punishment had been too great. Link could focus on studying a magic seal to heal the Realm Crack.
To increase efficiency, he didn't keep it a secret. He publicized the magic seal to all the Magicians there so they could all participate in the study.
There were hundreds of Magicians within the barrier. The weakest was at Level-7. Through their mutual effort, they successfully created a small experimental magic seal after 18 days.
Now, Link and the Magicians were testing it.
The healing seal was printed on a runestone of more than 20 centimeters long. Five Magicians were feeding their power into it. Link stood to the side, making precise adjustments.
