Mirror of Mental Prowess

It is rumored that one of these mirrors hung in Medivh's study during his descent into damnation and madness. Such a warning doesn't stop the more ambitious arcanists from attempting to create one themselves. The mirror resembles a normal looking glass, 5 feet tall by 2 feet wide. Power: If the user knows the proper command words, he can use several powers. He can read the thoughts (even if in a foreign language) of any person reflected in the mirror, as long as the owner is within 25 feet of the mirror. He can view other places as if using the clairvoyance spell, but vision can extend to other planes if the viewer is familiar with them. The mirror can be a portal to visit other places; after viewing a location through the clairvoyance function, the viewer can step though the mirror and arrive there. Others may follow him. An invisible portal remains where he came through and remains until he returns, 24 hours have passed, or the user closes it with a command word. Closing the portal traps the user in the other place. A creature with an Intellect of 12 or higher can notice the portal with a DC 15 Spot check. Lastly, once per week the mirror can answer one short question regarding a creature whose image is shown on its surface (giving answers similar to those from the legend lore spell).
