Dresden (Dennis) is a high elf mage, who sometimes can be seen conversing with a skull that has dimly glowing eyes. The players' group knows this skull houses the mind of an ancient sage, and it can be asked a question and it will, given time, answer with what he knows. The sage is most knowledgeable in the subjects relating to the supernatural, and especially with magical spells. The skull requires books and scrolls of new knowledge as payment. It has asked, at times, to be allowed to possess the body of the person asking for information, but nobody has agreed to this, so it's not known if it can really do so. The sage lived at least hundreds of years ago, if not thousands, so his information is very dated as far as history and such. The sage will answer to whatever name its owner gives it; Dresden calls it Bob.
