Magical power has never been without limit. Usually one is limited by the
amount of magical power he can conjure forth and hold in himself for an
indefinite period of time. Once this amount is exhausted, he must regain
his magical abilites through time, or other means. Those who shun order,
may try to use a spell that takes magical power from others around them,
and gives them a portion of that power. This spell is greatly disdained by
those who consider themselves true wielders of magic, since the amount
gained by the caster is less then that taken from others, and has no other
useful affect, hence, a portion of that magical energy is lost forever.
It is said that magic is limited, not only in individuals, but also in
this very realm, and if it is not used carefully, it could vanish.
