The Tome of Lorlaiven is a simple-looking book, bound in black leather with a small golden symbol centered on the front cover. The tome is about 1 foot tall, 10 inches wide, and 2 inches deep. Approximately 300 pages of fine, thin paper make up the book, most of which are covered with a smallish, most exquisite handwriting. The origins of the book and its name are unknown.

The Lorlaiven Tome is a consummate acquirer of knowledge. Using its various clairsentient powers, the tome has gathered an extensive amount of information on unique magical items and other psionically empowered objects. This "hobby" has kept the tome occupied for centuries, the rumored lifespan of this item. The tome can set down or remove this information (as desired) upon its own pages by some unknown process; the book does not detect as magical, and there is no known clairsentient power to accomplish this task. Whenever found, the Tome of Lorlaiven generally contains detailed descriptions on the workings and history of some two dozen items that last caught the tome's attention.

The personality of the tome is rather dry and boring, conversing telepathically in the equivalent of a slow, monotone "voice". All the book really cares about is the accumulation of knowledge, with the vagaries of morality left for lesser minds. The tome can be a helpful, pleasant personality, but would give little thought to sacrificing a person's life to gain a bit of knowledge.

Unless the bearer has scholarly inclinations, the tome will generally attempt to conceal its sentient nature. When finding a suitable "owner", the book may or may not reveal itself by conversing telepathically (the book never speaks). Otherwise, the tome will either attempt to possess the owner and place itself into more acceptable hands, or remain hidden and try to tempt the owner thru its written words. The tome is almost always on the hunt for a new item that has come to its attention, and will often provide written enticements for the bearer to lure him into tracking down the chosen item.

The materials of the book appear to be commonplace, but so far have proven impervious to fire (even magical flames) and to aging effects. All other damaging sources are saved at +5 due to the book's remarkable Ego score.
