Drakarion stood before the Anomaly of Misfortune and Fortune. Their only task was to contain the Anomaly so that it didn't harm the other students.
Seeing that the Anomaly wasn't moving though, Drakarion and the others weren't inclined to make a move either.
Why unnecessarily engage an Anomaly which was staying quiet?
Apparently Rodrick didn't follow the teachings as he went ahead and awakened the Hand of Destruction just as they were having a silent standoff with the Anomaly of Misfortune and Fortune.
Drakarion had his entire attention on the humanoid Anomaly before him while Paulina was on the lookout on the battlefield.
She was making sure no one would interfere in this, unnecessarily provoking the Anomaly which was standing still all this time.
Unfortunately none of them had much information about the Anomaly other than the basics.
