The Twenty Third Object is a dagger. It is just under 19 inches long, from the tip to the end of the pommel. The guard is conventional on one side, but has a rigid ring on the other, leading some to suggest that it is carried via this ring. Other scholars point out this would make it useless for combat, and its incredible degree of sharpness seems to indicate it is not a ritual object, but a practical one. The grip of the Object is made of two pieces of wood, cerulea by appearance, and are held in place with three rivets of brass. The largest rivet is closest the blade, while two smaller rivets lie adjacent each other, across the handle, closer to the pommel. Slightly toward the blade from these rivets, but not as far as the large rivet, is a small hole that is drilled through the entire handle, meeting a groove on the underside. The pommel has a wedge-shaped cross-section, and appears unwieldy due to its small size. On the ricasso (that part of the blade near the hilt) are some engravings, which are not in very good condition. They seem to show a bird or angel, under which are, arguably, the letters VR, and then under these a further two squiggles.
This is one of the most hotly contested of the Objects, because it has such a useful power: it cuts the arcane connections between corpses and their spirits. This makes it particularly useful for the destruction of corporeal undead. It does not do nearly so much damage as, for example, a Pilum of Fire, but it is certain that if it cuts an undead being, that being will be put to rest. For a very lengthy time this Object was a trophy in the hands of corporeal necromancers of House Tytalus, passed one to another as part of a complicated game. Eventually it was won for the Academy, in a wager against a Tytalus Archmagus, by a member of the Criamon Path of Strife.
This Object also seems to separate many faeries from their physical matter, to divest demons of the vapours from which they construct their bodies, and to rob spirits of their material forms. It has never been used to attack an angel, although several Tytalus magi claimed to wish to.
