Shadow Gate

The Shadow Gate was an artifact from Kamigawa that allowed a person to travel from one shadow to any other on the world.

It was given to Uramon by the Myojin of Night's Reach and later stolen by Toshi Umezawa. Among other rewards, Night bound the Gate to Toshi's body by turning it into a kanji on his chest. Apart from convenient traveling, the Shadow Gate made it possible for Toshi to steal That Which Was Taken from Konda.

Toshi's descendant Tetsuko Umezawa practices a similar magic.
