Apart from the study of the Core Spirit Runes, Shard also experimented with other "simple" attempts mentioned in Dr. Schneider's notebook.
Dr. Schneider pointed out that the power possessed by Circle Sorcerers is the power of thought influencing reality, and therefore, even without learning any Arcane Techniques or Sorcery, they could use their own power, the so-called "mind over matter."
The spontaneously used powers stemming from Core Spirit Runes were organized in ancient times and collectively referred to as "Arcane Techniques"; the power related only to thought and used spontaneously without learning was organized into a system and referred to as "Sorcery."
