If contact through a Trump is successful, both parties are able to talk to each other, and even see some of each other's surroundings. Either party may end a Trump communication, either by passing their hand over the card, or by an effort of will. During the contact, each person has the option of reaching through the link to make physical contact, generally for the purpose of pulling the other person voluntarily to their own physical location. This is sometimes called "trumping" a person to the other location. In some cases, one can also travel via Trump to the other person's location without the other's consent or assistance, as long as the contact remains open (e.g., Dalt's attempt in "Blood of Amber" to come through a Trump held by Merlin, which failed only after Merlin summoned the Logrus to sever the contact). A Trump contact also creates a potential opening for an attack by either party on the other, either with a weapon, or by using the link in an attempt to dominate the other by sheer force of ego and will. This can result in immobilization or worse for the victim of the attack.
