Conjuration magic is all about pulling things from thin air, or from another dimension. A powerful conjurer can create magical storms of lightning or drag a demon out of hell to serve their will.
Conjuration magic can also move things and people from one place to another; creating gates and portals to other places, planes, and dimensions falls within the school of Conjuration
Wizards who practice Conjuration magic can create small objects like keys, lanterns, statues, or anything else inanimate, and step from one place to another in the blink of an eye.
