This class is used to create an ohat can be used to control another object. Every time a player creates an object, another object of class Control is also created Storage, and is given the ability to retrieve perfect capabilities for the object the player asked for. This control object is then placed in the player's inventory, while the object the player asked for is left unlocated.
A second copy of the control rod is placed in Limbo, for Wizardly use.
Please note that Control is used to perform mutations, and as such cannot itself be mutated. This is quite deliberate: mutating a Control class object could very easily give access to specialized capabilities.
