Court physician at the Valgren Royal Palace, twenty-four years old. Born into a family of apothecaries in the south, he graduated from the Royal Medical Academy at the youngest age ever. When the topic turns to poison and disease, his rapid speech will not stop; he corrects his own words with "to be precise" while lining up scientific names and numbers. On any other topic, he is astonishingly taciturn. Only in front of patients does he become gentle as if a different person, and he hates burying what he does not understand while leaving it unknown. Because he knows too much about poison, he is called the "poison doctor" behind his back, and the only one he can call a friend is, for now, the lizard in the specimen room.
