i feel like trying to figure out what magic is fully now, and this is mostly assumptions here. id assume magic is a force, inside and outside the user, originating from the soul, floating about them, able to be channeled into many things, manipulation of things, the ability to create things, such as attacks. i will assume that when creating these physical objects, you are condensing the magic into a stable, visible form, thus creating, lets say, a bone. this bone can be freely controlled by the summoner and maybe even other monsters that share similar magic, when this bone is, "despawned" it seems to simply vanish into thin air, id think its dissolving back into pure magic and collecting back with the summoner, or simply dissolving into the air and floating away.
