Doppelganger Mirror

I was reading through the Swords & Wizardry rulebook and an idea popped into my head. I'm not sure what trigger the idea, but here it is. The Doppelganger Mirror is a nasty little item to spice up a campaign. Even the destruction of it is going to cause problems for a long time. Enjoy.

The Doppelganger Mirror is made of a high quality, polished glass. It is framed within a large oval silver steel frame. The frame is sculpted in a sea theme with waves adorning the edges and clam shells at each corner. It weighs 100 pounds and is meant to lean against a wall for support. It looks to be of elven craftsmanship, but its weight and thick frame suggest it is only elven influenced.

The mirror reflects a depth to objects and people that regular mirrors are incapable of doing. The mirror is able to see around things. When a person stands before the mirror and desires something that object or thing will appear in the reflection.

If the player concentrates on the object the surface of the mirror will begin to ripple. At this time the player can reach through the mirror's surface. If a player chooses to do this he must make a saving throw vs. spell or be imprisoned within the mirror. The doppelganger of the player is now free to move through the real world. This doppelganger has gleaned most of the surface knowledge from the person, but does not know the background or secrets. It will use its ability to read minds to find more information. A character can resist this with a successful saving throw.

The doppelganger will provide substance for the imprisoned player by bringing drinks and food within the range of the mirror's reflection. It is in the doppelganger's best interest to keep the prisoner alive. If the player dies then it dies. The player can interact with the objects that are reflected in the mirror and use them as they normally would. However, magical properties cannot be transferred through the mirror. A +3 sword would be a regular sword within the mirror.

Once the mirror has taken someone it reverts to a normal mirror until that person dies. Only the doppelganger can see the prisoner within. To all others it is just a fancy mirror.

Only a magical weapon or object can shatter the mirror. Smashing the mirror will instantly kill both the imprisoned and the doppelganger. The magical explosion will tear through the fabric of reality making the affected area weak.
