Prana

The Plana is an almighty power wielded by Aigami, Sara, Mani, and a many other unnamed characters in Yu-Gi-Oh! The Dark Side of Dimensions. It is described as the ability to bend reality to the user's will and to create a world without evil or fear. According to Shadi, it was bestowed upon Aigami's group when Atem departed for the afterlife. However, should the pharoah ever return, they will lose the Plana forever, which ultimately drives Aigami to attempt to kill Yugi.
