   Summary

   As his Sixth Year in Hogwarts starts as any other of his years would start, Veritas Ratio, a renowned student by all known for his intelligence and thoughtful mind, assists the arrival of a freshly new and unknown student ; Aventurine, a charming boy whose origins and past remains unknown to all. His success is immediate, yet everything about him stays blurry. Ratio could just get over him, as he gets over all the other students.
   But the boy starts to act in an interesting way, trying to subtly get closer without delivering any information about himself. And Ratio is simply a man. A man who seeks knowledge, truth. A man who finds interest in interesting things or topics.
   Aventurine is his new enigma, his new puzzle to complete.
   But what will he discover by gathering all those pieces ?
