The Lich belonged to high-ranking races and generally possessed powerful magic.
However, that was secondary.
Whether they were Angels, Demons, Dragons, or Titans, all other high-ranking races understood one thing: never provoke a Lich unless absolutely necessary.
If provocation was unavoidable, a quick fight was the best strategy; never drag it into a prolonged battle.
This race had many characteristics that were completely different from other races. For example, they had almost no clear desires, often living in confusion. If someone offended them, it undoubtedly gave them a clear target. *They would be thrilled to the point of madness and devote all their efforts during their near-infinite lifespan to defeating their opponent and settling accounts.*
