Cássio was born in Portugal in 1990. His biggest struggle as a writer is not creating a character inspired by his cat, Oli, in every book he writes. While he studied robotics, his passion for languages led him down the path of teaching and interpreting. A fusion of science, languages, and a love for his cat, Oli, has molded him into a sci-fi and litRPG author who specializes in clean, wholesome fiction. In his free time, Cássio enjoys leisurely walks with his beautiful wife and playful moments with Oli, the two muses behind his writing.
