Osirionologists & the Practice of Osirionology
A practitioner of the discipline is an Osirionologist. The subject is so broad that many types of Osirionologist are found: most are academics or archaeologists, but some are necromancers, linguists specializing in hieroglyphs, or modern Osirians looking for their ancestors' treasure. Some Osirionologists are specialists while others preserve a much broader aspect of the discipline.
