Thomas Anstey Guthrie's Stone

Description
A polished white and black stone with the depiction of Yin and Yang carved into the stone.

Origin
Thomas Anstey Guthrie was an English novelist and journalist, who wrote his comic novels under the pseudonym F. Anstey. Although he excelled in comedic slants and parodies, his most famous work was the novel "Vice Versa". During the tale, a distant father and abused son end up receiving a magic stone capable of one important wish. The boy decides for him and his father to switch roles and inhabit each other’s lives. Afterwards, they are returned to normal with a better understanding of each other’s situation.

Effects
When in use, the yin & yang symbol glows and moves in a circular fashion. By itself it can allow mind transference; when used with other artifacts, the stone can allow energy and item transferal, effectively letting objects or their energy states swap position.
