So, my question is pretty simple: Does shadow magic still exist in the world? I've seen nothing to imply that it DOESN'T exist, but it's not really mentioned outside of Shadowkey and it's obviously not displayed as a School of Magic in any other TES game.
Does this mean that the art of Shadow Magic was lost after the War of Bendr'Mahk? Or is it safe to assume that it is still in the world of TES, but just not displayed in the games? Or is it simply something that was just dropped after the dismal sales of the N-Gage and, thus, Shadowkey? And if that is the case, how much weight should we apply to the "Canonocity" (copyright KT01 2008) of Shadowkey?
So many questions....
