Raenef IV

He is the previous Demon Lord Raenef. A powerful Demon Lord, he specialized in incantations, written spells that increase the user's power tremendously when memorized or written correctly. Much of him is shrouded in mystery, particularly the circumstances of his death. Though he is portrayed as eccentric and even a little mischievous (particularly by a very irritated Krayon, who had to "tutor" the younger demon lord in years past), he is ruthless and somewhat self-serving. Though he has been dead for some time, his spirit still appears, though the older demons Meruhesae and Krayon don't seem to be particularly ruffled by his apparition. It is revealed that Raenef IV caused his own death to avoid a powerful curse, called "the Destruction of the Name," placed on him during the war. He had a particularly close relationship with Eclipse, which could echo the latter's growing bond with Raenef V. (Source: Wikipedia)
