History
The Land of Mad Silence is an alternate dimension that is apparently an afterlife of sorts for the souls of the dead. It's origins and that of it's keeper, the so-called Guardian of the Spirit World are unknown. It is possible that it is an other-dimensional realm of some unspecified pantheon of gods.
In 1942, mad scientist Dr. Igor Korbeau created a device which allowed him to banish the souls of the living to the Land of Mad Silence, leaving their bodies mindless drones that he then enslaved. He tested out his device on a number of scientists who discredited him in the past. The other-dimensional hero known as the Vision travelled to the Land of Mad Silence and fought the Guardian of the Spirit World in order to free the souls, returning them to their rightful bodies.[1]
The current state of this realm since has yet to be explored.
