Within the larger school of Conjuration magic is the subschool of Calling. This subschool specializes in spells that instantly transport creatures to the spell caster's vicinity. A "called" creature actually dies if it is slain, unlike creatures brought by a spell from the Summoning subschool.
The calling subschool is an invention of the "3.0" edition of the Dragonlance game.
