Illusionism is a sub-branch of Battle magic that deals with spells designed to deceive the senses. These enchantments can be a great boon on the battlefield, where enemy forces can be made to see troops where they do not exist or to see woods where there are soldiers. Unfortunately, illusionism also has great potential to be used for nefarious purposes and sometimes comes uncomfortably close to Dark magic. Illusionists' activities are closely monitored by most Old World governments and some Illusionists work directly for the local noble or ruler, or an influential power-bloc, or even the Emperor or his agents. Sometimes this is in a military capacity, but, more often, they find themselves being used as spies, assassins, or in other covert and less than respectable operations.
