Mirror of Mental Prowess

Wondrous item, legendary

This mirror resembles an ordinary looking glass 5 feet tall by 2 feet wide. If you know the proper commands you can cause it to perform as follows.

• Read the thoughts of any creature reflected therein, as long as you are within 25 feet of the mirror, even if those thoughts are in an unknown language. This is similar to casting the spell detect thoughts.
• View other places that you are familiar with, even locations on other planes.
• Use it as a portal to visit other places. You first view the place, then step through the mirror to the place pictured. Others can follow you through the mirror if they like. An invisible portal remains on the other side where you arrive, and you can return through that portal. Once you return, the portal closes. The portal closes on its own after 24 hours (trapping you if you are still in the other place), and the you can also close it with a command word. Creatures making a successful DC 14 Intelligence (Investigation) check can notice the portal. Any creature who steps through the portal appears in front of the mirror.
• Once per week the mirror accurately answers one short question regarding a creature or object whose image is shown on its surface (giving answers similar to those from the legend lore spell).
