Belphinius Mendellix, known as Phin by his friends, was a Raintaster's son who entered the Knights Academy. Phin became an academic-at-arms and a close friend of Quint. He helped Quint to stop the Endless Winter threatening Sanctaphrax, and took up a position aboard the Galerider during Clash of the Sky Galleons. In the events of clash of the sky galleons Phin helped harvest the gigantic flight rock from the stone gardens to make the bringer of doom, a Leagues ship. Phin probably came from a rich backround as only the wealthiest families could afford to send their sons to the prestigious knights academy in Sanctaphrax. Phin was the swordsmaster in the academic-at-arms corp, and was described as the finest that they ever had, after Vilnix Pompolonius dismantled the knights academy, Phin probably had to find work somewhere else as this meant that the academic-at-arms were no longer needed.
