Demi-Lich

"These proto-lich undead creatures are midway through their dark transformation into full Lichdom. At this point, the creature is nothing more than a floating skull, though many wizards undergoing this metamorphosis tend to adorn their skulls with gems and precious metals. It's a dispicable practice and a sign of great internal evil to attempt the rituals of Lichdom. However, there is a temptation that all Human wizards feel... One that cannot easily be ignored." - from the journals of Old Jass
