Domination Link

This spell functions like detect thoughts, with the additional ability to find echoes of the thoughts of a creature mentally controlling the target. For example, if the target has been dominated by a vampire, you can use evidence left in the target's mind to learn about that vampire. Each minute you concentrate on the spell, you can learn your choice of one of the following pieces of information.

All of this information is based on the last time the influencing creature linked itself to the target, either to issue a command or to receive sensory input from the target. For example, if at nightfall a vampire commanded a dominated victim to walk to a cemetery, this spell can reveal the vampire's general location at that time, though it may have moved since then.
