After the battle and the celebration of victory was over, the trainees and novices began to prepare themselves for the next part of Hera's plan.
Arwin was the one working the most there since he needed to melt all that ice that he himself created to trap the ship. Also, he was using his Mystical Art ice craft to repair the ship as fast as possible.
Of all others participating in that battle, Arwin surely was the MVP. He was not only a key piece to their planning, but he also fought exceptionally during the confrontation on top of the deck. Thanks to him and his spell that reached a long range, he could save a lot of trainees and novices, preventing them to have more casualties.
If Arwin wasn't there, they would have lost more than only two trainees on that battle, that was for sure. The orcs and kobolds weren't enemies to be underestimated. Just a few warriors fighting on that deck could fight on even grounds with them.
