Hvetshranology is the science that studies the Hvetshran species. People who practice this are called Hvetshranologists.
History[]
The first Hvetshranologists called themselves Demonologists still, studying the Hvetshran species among the countless existing demons, or vampires. C. Sadler and E. Cardwell are however still regarded the first two, and many Demonologists from the seventeenth century can be classified as both, depending on which works are taken into account.
The first people who explicitly mentioned to be studying or even teaching Hvetshranology date only from halfway the eighteenth century.
