Moving from another dimension where the spirit form is to the other dimension where the real form is. In order to try it out with a random pebble he made an image where he was holding it, then just like the brooch, he was able to summon it to his own dimension. When he touched it, it wasn’t like the vague feelings he had before, it had a firm feel. The concept of distance seems vague, when summoning it to his hand it’ll be there, if he imagines it to go far away it’ll go far away. Thinking of it as a storage place it’s a very useful infinite place.
