Trumps are images which possess a link to the being or place depicted. Anyone can attempt to use a Trump, even shadow dwellers. Being cards enable you to open a psychic link across Shadow to the being depicted, if that being consents to the contact. Once such contact is established, you can talk, engage in psychic contact, pull each other through the link to the puller's location, or even try to kill each other. Place cards allow you to instantly transport yourself to that place. Few people can make them, but somewhat more know a variety of simple tricks that can be done with them, from Trump Prediction (using them as Tarot cards) to Trump Caller ID, which is quite useful for avoiding hostile Trump calls. Trumps are traditionally the size of Tarot cards, but also may take the form of paintings, engravings, charcoal sketchs on the wall, sculptures, or almost anything else which involves imagery. Rumors whisper of VR Trumps for high-tech universes, Trump music, Trump architecture, and other strange forms.
Properly created Trumps are nearly indestructible. Pattern cannot mold or destroy them, Logrus users get shocked if they touch one with a Logrus tendril, and Magick simply rolls off them. Shapeshifting will not prevent a Trump of you linking to you, regardless of what form you take on, except perhaps if you attempt a Persona Shapeshift and lose control to the artifical persona. It is possible, however, for a Trump in use to be destroyed if a weapon or other object is currently being extended through the link when the link is cut off.
Trump, as a Power, is stronger than Logrus or Pattern at their weakest, and weaker than they are at their strongest.
Lost decks are not easy to replace, so try not to drop them all in the Abyss.
This link allows the passage of items back and forth, physical or mental assaults on each other (opening oneself to Trump gives them a free psychic contact which can only be broken by them chosing to close the link or by some trick which disrupts psychic or trump contacts), or even physical travel--either the caller or the recipient can pull the other person through the link. Several people can be pulled through if they join hands.
When a Person Trump is active, you can see past the person 'on the other end of the line', gaining a somewhat obscured view of what is going on around them, although much of your view is blocked by the person himself. This has the flip side that when Person Trumps are used, you can't see your own environment; it is not safe to answer Trump calls under stress or in combat. You won't even hear people talking to you unless they touch you, in which case they're patched into the Trump contact for good or ill.
If the recipient of a Trump call choses to refuse contact, it takes a severe Psyche advantage to force such a contact. If the victim is familiar with the art of Trump Defense, it becomes virtually impossible to force the contact while they concentrate on it. Logrus Defense and Pattern Defense will also make forcing your way into someone's brain nigh-impossible. Items which convey Psychic Barriers and the like are also handy.
Those who have studied the art of Power Words can learn 'Trump Disrupt', a Power Word which will deactivate Trumps and break Trump Contacts.
