Fervidius Tharn

was a well known member of the Tharn Family who lived during the middle years of the First Era. Fervidius was a prominent member of the Alessian Order and was even known to be the Arch-Prelate of the Alessian secret sect known as the Marukhati Selective, being given the title in the year 1E 1188. Fervidius was best known for writing the book "Sermons Denouncing the Seventeen Leniencies".

Due to his writings in the book On the Detachment of the Sheath and the year in which he was the Arch-Prelate of the Selective, it is safe to assume that Fervidius was responsible for the Middle Dawn Dragon Break which occured in 1E 1200.
