Nobody but other Sages could intervene in a fight meant for Sages.
The participants and the infiltrators both pulled back and allowed the two Sages to duke it out against each other. This was not a fight they could participate in. Instead, they chose to fight opponents of their own caliber.
Hansen and Gregory disappeared from their places and appeared to be fighting in the sky. They both reached a high altitude before letting their spells take effect around them. It was an understanding shared by both Sages for the younger generation.
The rankers awaiting them on the sidelines got involved in the fight when the infiltrators who stood with Gregory entered the fray. Of course, compared to Edinburgh's rankers, they were very few. So it was only a matter of time before the infiltrators were handled.
However, both sides didn't know a third force would involve itself in this two-way conflict. And it was about to make the conflict even more multi-faceted and dangerous for them all.
