The sorcerer's last words

In the aftermath of the notorious event of the enchanted broom, the Sorcerer's Apprentice learns his lesson indeed: "Seek Truth, not Power," is the Sorcerer's dictum. Peace returns to the castle's long days, but as obedient Humboldt grows older, a madness grows in his master. The sorcerer has discovered strange secrets in the depths of the library. Humboldt's dreams, too, are haunted by the broom, and the gods of wood, water and straw whisper through the halls at night.
