After traveling approximately 100 meters, Atticus and the other trainees heard a deafening explosion coming from the direction they had left behind.
Though they were tempted to look back, Atticus didn't pause for even a moment. He continued to manipulate the earth platform they were on.
Seconds later, the shockwave from the explosion reached them, and Atticus swiftly erected a wall at the back of the platform, using the force of the shockwave to propel them farther away from the scene.
There were about 50 trainees onboard, most of them were first-years. A few second-year students, including Sophie, were also present, but the third-year students were in the minority, numbering just 10.
This small group included individuals like Sirius, Helodor, William, and his three subordinates, Jack and his companions.
Since they were already situated on the east side of the camp, they didn't need to pass through the camp grounds again.
