The Guild of Healers were one of the major 18 guilds of D'ni and were primarily tasked with treating injured and sick residents, equating them to the Human equivalent of doctors. During the reign of the Great King Ahlsendar, the Guild of Writers and Healers were working on a plague, in order to be used as a biological weapon in case of eventual emergency. That plague eventually destroyed the Pento. Grand Master Hemelah was appointed by King Kerath as one of the first Five Lords of D'ni.
