The Story of Néro & Sci

Néro is a young Synapsian who lives on the streets of Curiosita, the capital of the world of Heméide, home to a people wallowing in their achievements. He has taken refuge in the library of Psyga, whom he considers like his father.

While cleaning out the basement of the library, Néro drops a jar containing Sci and knocks over a book that unleashes the Chaos theories and plunges them into the caves of Heméide, from which they will have to escape!

" Mathematics is a gymnastics of the mind and a preparation for philosophy." Isocrates .
