Throughout the ages, what we now know as civilization has come about through only one means, knowledge. Knowledge comes in many forms, and in many different fields. Many of the most powerful figures in the realms today, have not fought for their positions as much as they have gained them through knowledge. Magic, from its inception, has been an unparalleled tool in gaining knowledge. Any magical spell that allows either the target or the caster to know something previously unknown, is part of this family of spells. The only real prerequisit to cast this type of spell, is the thirst for knowledge.
