Bristlebane's clouded mind barely heard the words, running for over an hour was no easy task and his legs felt like lead at this point. He had no idea how this was related to learning magic but he didn't really want to question the master to find out. He could hardly keep his eyes open to avoid tripping on the slope and randomly scattered slopes. He hoped the others were having an easier time of this, and that they didn't have to do anything after this. Bristlebane wasn't sure if he could do anything but sleep after this exhausting workout, the slope wasn't very bad at first but over so many laps it really started to wear you down.
