Lore
''The true essence of Fire lies at the edge of Energy and Matter. It is, therefore, a fairly simple matter to shape Mana into a magical flame. Controlling a bolt of this fire as it flies towards its target is another matter entirely. As experience and knowledge with this spell grows, both the intensity of the flame and the speed of the bolt can be increased with the caster feeling less exertion.''
