He saw the magic wand in the other hand, and the purple crystal on the staff head, and suddenly understood what this Skeleton was.

Mortals find it difficult to withstand the erosion of magic power, which is why Magic Guided Engineering and various related professions were developed.
But in ancient times, there were some magicians who risked their lives to study the spells of fairies, elves, and dragons. They discovered a method that could allow their bodies to endure the power of Ether Magic, which was to abandon the frail human body and transform themselves into undead.
The school of Undead Wizards is probably one of the most peculiar in Eteliria of this era, and those who practice undead magic likely have one ultimate goal—to eventually transform themselves into a vampire or a sorcerer-ghoul like this skeleton in front of them.
These ancient magicians indeed gained magical abilities, even without the aid of Magic Guided Reactors and alchemy.
