The Citadel of Shadows
King Litch V
"All I want of you is that you go forth into Ardania and tell them King Lich V is BACK!"
“Many assume the number ‘V’ after the name of this king means there were four other lich kings before him. But this is something of a misconception, for there has only been one Lich King, and the number instead represents how many times he has been resurrected. It is in part in a warning to his enemies, a reminder that the vengeance of the undead King can never be entirely avoided.
And if one considers that King Lich has unparalleled skill in magic, it becomes rather obvious why he has so few enemies."- From “The Overall Description of Everything” by Master Alfus Bumblegate
