Mirror of mental prowess

A mirror of mental prowess was a type of enchanted mirror that could be found in the Realms.

Description
A mirror of mental prowess largely resembled an ordinary mirror. On average it measured about tall and  wide.

Powers
These mirrors had a variety of magical abilities that could be accessed by stating the proper commands. These abilities encompassed the following:
 * Allowing one to read the thoughts of any creature reflected therein, regardless of their languages, as long as the owner was within  of the mirror.
 * Scrying with it as though it were a crystal ball with clairaudience. The user could even view into other planes if they knew them sufficiently.
 * Acting as a portal to other locations and even other planes. The destination needed to first be scryed and afterwards an invisible area remained on the "other side" that acted as a portal back. This portal would close once the owner returned, once the owner used a command word, or otherwise would close itself after a period of 24 hours.
 * Once per week, the mirror could be made to accurately answer a short question regarding a creature whose image was shown upon its surface.

History
Circa 1357 DR, a mirror of mental prowess stood within a temple of Moradin inside Illefarn.

In 1367 DR, a large mirror of mental prowess stood within the library of Zarastro's castle on Zarastro Isle that was guarded by the green hag Xana.
