This section of the Codex covers the complex topic of conjuration and summoning. Conjuring deals with transporting creatures, or a magical duplicate from another plane. It also deals with healing, creation of objects at that moment, and so on.
It's worth noting that no matter how much the caster might want to, objects and creatures cannot appear inside another object or creature. That just isn't done. Neither can they appear floating, unless they are something that already floats!
