"The headmaster will look after the cleanup for now, the rest will search the island for any remnants, and those who were done with their task will either return to the academy, or in the other districts."
The creature that resulted from this process was a being with high Magic resistance and near immunity from the physical attacks.
'The people that were fighting this being, including the organisers and the people who helped the headmaster were all specialists with strong abilities.'
