Magicians, Druids, Vampires, Wizards.
Liszt had already encountered four kinds of special Casters.
In the leftover notes from Curtis Truth, there was an illustration of the Eye of Truth, in which the three corners of the triangle represented matter, Magic Power, and spirit, each one listing out the relevant Caster professions.
In the material branch, there were Alchemists, Vampires, and Necromancers.
In the Magic Power branch, there were Magicians and Druids.
In the spiritual branch, there were Wizards, Sorcerers, Prophets, Succubi, and Shamans, among which ancient Wizards mostly transformed themselves into Liches, which is to say, Curtis Truth and Andy Sapphire of the Marquis of Bull, belonged to the category of Wizards.
It was unknown if these Casters really existed.
