This device created by Sith alchemy from ages past is a large full-length mirror that is intended to be hung from a wall. The Mirror of Anor is a shining silver ovoid that is 7' high and 3' 6" wide. The surface is unblemished and remains so even in the harshest environments and conditions. The frame that surrounds the mirror is a grayish silver resembling pewter, and in it is carved a beautiful and extremely intricate fresco of past Dark Jedi, that flows around the mirror and back into itself. The detail is amazing and unmatchable even by modern technologies. Upon close enough inspection, even the textures of the clothes have been included.
The surface seems to be an analogue of transparisteel, but reveals itself to be much more. All the qualities of the substance are unknown and it has resisted attempts at reproduction. Lightsaber blades are simply absorbed at the point where they touch the substance. Unlike cortosis fiber, the blade is not disrupted or dissipated, it simply ceases to exist where it comes into contact with the mirror, without disrupting the function of the rest of the blade, almost like it goes through the mirror without actually causing any damage. The same holds true with blaster bolts and any conventional weaponry.
The Mirror of Anor was crafted by the evil shaman witches of Dathomir, both as a resource and a tool to trap their victims. Once their own uses with it had finished, they allowed it to be stolen by treasure seekers, and since then, it has circled the galaxy, entrapping many more with its cursed powers.
Imbuing the Force into the mirror causes the fresco to animate, and voices of the spirits trapped inside can be heard. It is possible to focus on one and bring it forth from it's fellows; eventually the image of the speaker will appear in the mirror. Lesser Jedi must stop and satiate their curiosity with questions of the past. More powerful practitioners could give the spirit a physical form. This requires a mortal body or clone for the spirit to inhabit, and the expenditure of such an amount of Force power that even a Dark Prophet might be helpless for the next few hours. No one may call forth more than one spirit at a time.
The spirit resumes physical form with full knowledge of the skills it had in life and is bound to the protection of the one whom called it forth. It will obey any order without question, and will sacrifice itself in the pursuit of protecting its summoner.
The spirit, in order to sustain itself, must feed on life energy from others by draining away their personal stores of the Force. A person can usually survive this for about a week before perishing, and the spirit may choose no other prey before finishing someone. Even more sinister is that after bringing a spirit forth the Jedi who summoned it shares it's habits of preying upon the life-force of others. The Jedi can choose any source to draw the Force from, including plants, animals and even Force imbued objects to the level of his ability. He will carry the curse to the end of his life. Even if the spirit summoned is returned to the mirror through destruction or a lack of feeding the Jedi still needs to feed as he has forged a (so far) unbreakable connection to the Mirror, which siphons Force away from him and will kill him if not shored up with other sources of energy.
Finally, the curse of the mirror does not end after death. Once a Jedi who has made use of the mirror dies, his spirit becomes enmeshed in the mirror and his image appears entwined in the fresco to be summoned up by future users, guaranteeing an increasing supply of luminaries to tempt the next user. So far no negative effects have been found from merely calling up a Spirit for questioning.
