Against All Odds
Also known as The Touchstone of the Spheres, this object looks rather primitive: An irregularly shaped polished black stone with stars, spirals, and geometric designs etched into it. It is usually kept in an old oilcloth, due to the belief that touching it is potentially dangerous if done frivolously. Agatha Landau touched it using Psychometry and got a powerful impression from it: That this artifact had once been kept by Ventrue himself.
The Touchstone acts as a sort of bridge between planes of existence. For example, James Smith accidentally used it to peer into Hell and see Ezahimon in one of his demonic forms.
