Lich.
This term, or rather this type of artificial creature, originated from ancient times, possibly beginning in the Moon Empire—yes, it seems that everything in this world is eventually connected to the Moon Empire, as if there was only one human nation in the ancient era, which was the Moon Empire itself.
In some Magic Books of magicians, the Moon Empire is described as a realm in pursuit of magic, and thus gave birth to a wide variety of magical professions.
Just as recorded in the book he obtained from the Ghost Ship, "To His Highness Annuette—Curtis Truth," surrounding the triangular symbol of the Eye of Truth, there were professions like Alchemist, Vampire, Necromancer, Magician, Druid, Wizard, Sorcerer, Prophet, Succubus, Shaman, and others.
All these professions have been obliterated by the river of history, with only magicians continuing to exist.
