Unique to the Tower at Van'dyal Forest, a creation of magic gives the tower itself an aspect of life. This is the Master of the Tower, and though tied to the grounds, he knows everything that happens within.
The Master possesses several unique abilities, such as the ability to discern the location of anyone and everything within the Tower itself (though not necessarily just within the grounds or in the forest), the ability to communicate telepathically with any sentient creature within the tower (even if such creatures are normally immune, though this does not extend to constructs), and the ability to mimic any person that has ever Tested within it. The last ability is particularly potent, as the Master can access any knowledge or abilities that person had when last within the Tower. Obviously, this may not be current, but can provide vast insight into mages long past.
