Created by mysterious figures who are more powerful than we can a imagine, the ‘gateway’ mirror as it was dubbed by one of its owners, is a mirror that looks ordinary however once every 100 years it will show anyone looking at it a version of them in a alternate universe for example a universe where they were born as the opposite gender, a universe where there parents had them later in life which would make them younger or vice versa there parents having them earlier in life making them older, they can even see a universe where there are half animals half human people, with infinite universes the possibilities are endless.
If one was to touch the mirror they and anyone in the reflection of the mirror would be trapped in the alternate universe the mirror shows them and they would have to live in the bodies of their alternate universe selfs.
The mirror was bought in the magic shop over 105 years ago however it was lost and the owner went missing.
