You have the ability to build a mental image from the mind of another person. You must in some way be in contact with the individual for a minute to gather the necessary data. It can be a voice or video call, but the contact must be direct and in realtime. Once you have identified the person, you will get a instinctive, mental image of what the person looks like (if it was voice only) and what they call themselves. Do note that if the person is acting under pseudonym, you will get the person's real name, rather than the pseudonym, as you are probing their mental identity.
A psion with Mental Shield
