For 10 points, identify this native of Castalia whose skill at the Glass Bead Game leads to his becoming the Magister Ludi.
One of this man's poems describes how he read of "How Adam also ate of the other tree" in the book The Squaring of the Circle--Final Stage, while another tells of how he "cannot be dislodged or misdirected / held in the orbit of the Cosmic Soul". He also wrote three false autobiographies entitled The Rainmaker, The Father Confessor, and The Indian Life. His privately-directed studies of Swabian Pietism led to a humorous conversation about Johann Bengel with the historian Father (*) Jacobus. He had earlier studied under Elder Brother at the Bamboo Grove hermitage after being plucked from Berolfingen and sent to Waldzell. He dies after taking a cold swim two days after becoming the tutor of Plinio Designori's son Tito. His friends include Carlo Ferromonte and Fritz Tegularius, and he succeeded Thomas van der Trave at his highest post.
