Elemental light is one of the greater elements, alongside Darkness. Light is the opposite of Darkness, but the one also cannot exist without the other. The greater elements are considered to be the essence of balance in the universe.
Light magic can be used to create light. At lower levels, it can be as simple as calling enough light to guide your way. At higher levels, it can be used to blind someone.
It is very important to note that light is not necessarily associated with good. Light can exist in cold, and light can be shed harshly upon things.
Light elementals appear either as flecks of light, or beings made of light. They have very differing personalities. The elemental guardian of light is a fox.
