Apart from Shard, all other students were formal students attending the Academy, wearing the standard black robes as their uniform.
Professor Garcia briefly welcomed Shard and then began the formal lesson. Of course, he first explained the assessment requirements of the course and gave instructions on the course report, which had to be 12 inches (about 30.4cm) long on parchment.
Shard had thought that he might not understand such a specialized course since he was attending it early, but after Professor Garcia formally started the lecture, he discovered that the course was simply a rudimentary introduction to "Maze Lock," a peculiar kind of supernatural ability.
Circle Sorcerers who chose this course were planning to study Arcane Techniques or Sorcery related to Maze Locks, or at least had that intention. Relatively speaking, Shard had a stronger understanding of the course itself because he had actually used a Maze Lock more than once.
