This was called the LICH in pre-production as explained by Wikipedia: In the Dungeons & Dragons game, and in many works of fantasy fiction that draw upon Dungeons & Dragons for inspiration, a lich is a spellcaster who seeks to defy death by magical means. Liches convert themselves into an undead state by means of black magic and necromancy. As a consequence, the only permanent way to kill a lich is to destroy its phylactery; otherwise, it will be able to recreate a new body for itself. Occasionally, this metamorphosis occurs by accident as a result of life-prolonging magic. A lich retains the abilities that it possessed in life, but it has a virtual eternity to hone its skills and inevitably becomes quite powerful. Liches are usually among the most powerful undead creatures in almost any setting in which they appear, and are one of the most powerful non-unique undead creatures in the Dungeons & Dragons game. If a lich exists long enough it becomes a demilich. The demilich's interest turns away from the physical realm, instead using astral projection to travel across other planes of existence. The magics preserving the demilich's body against the ravages of time weaken, usually causing the body to gradually deteriorate until only a skull or even a single skeletal hand remains.
The character of Lord Voldemort in the Harry Potter series stores fragments of his soul in a very lich-like manner; evidence from Harry Potter and the Half-Blood Prince spells this out. Whether or not he actually qualifies as a lich is a subject of debate, as his body is living, not undead. Skeletor(Masters Of The Universe) may be considered a lich, because he possesses a skullike face and magical abilities. Since he was mortally wounded and then immediately brought from the brink of death and transformed by dark magic, he may qualify as undead and uninterred. Or
