Exiled Mages are powerful mages imprisoned and banished through time by the leaders of an order of Runemasters for their crimes.
Free them from their Rune Prisons if you dare, as untold eons of imprisonment may have driven them mad. The knowledge of the Exiled Mages can be found in the form of powerful items they experimented with, though this knowledge shall remain if you do not accept the risk and free them.
Through Woven Echoes, you may be able to learn the secret to crafting your own Experimental Items.
