You create an ethereal psionic sensor, vaguely humanoid and ominous in stature, that relays visual information
You can summon an ethereal agent at any point you can see. It then immediately re-forms on the Ethereal Plane and can travel beyond your line of sight without hindrance. Even while outside your line of sight on the Ethereal Plane, it explores according to your mental directions. The agent travels at 40 feet per round (400 feet per minute) if viewing an area ahead as a human would (primarily looking at the floor) or 10 feet per round (100 feet per minutes) if examining the ceiling and walls as well as the floor ahead. The agent travels in any direction as long as the power lasts.
You must concentrate to use an ethereal agent. If you do not concentrate, the agent stand inert. Once your concentration lapses, the power ends after 5 rounds unless you renew your concentration. An ethereal agent can pass through solid objects, but it can never leave the Ethereal Plane. It can be seen and attacked by anything that can see and attack an ethereal creature. It has an Armor Class equal to 14 + your Dexterity modifier and can take 10 points of damage before being destroyed.
An ethereal agent can see normally but also has darkvision out to 60 feet and blindsense out to 30 feet. It uses its own senses to view its surroundings. Because the agent resides on the Ethereal Plane, the perception of the corporeal world it relays to you is somewhat blurred; you can make Spot and Search checks through the ethereal agent while maintaining your concentration on it, but those checks carry a -2 penalty.
