Objects have a high concentration of magic within them, it's what makes us sentient. We like to call the center of it either the heart, soul, or nucleus.

It's what keeps food from going bad, technology from losing its battery, and so on. Magic can also connect us to certain aspects of our object, so a glass of juice may feel nauseous when it's empty, or a phone's memories can be accessed through its hard drive.

Our magic is also unique to the individual due to its ability to hold a conscious, so I guess you could say it IS a soul. We call these magic IDs. They can be registered into a recovery center so it can recognize who's who.

When an object's magic is released into the air, it can then be picked up by a recovery center if their name/ID is typed in. Due to its relation to itself, it will stay intact despite it being free from its vessel. If an object is not recovered in a long time, they will eventually diffuse back into the air as regular magic.

Our faces and limbs are constructed by magic, same way a recovery center uses magic to reconstruct objects. The texture of our skin can vary based on the environment of our conception, so it can be rough, smooth, fuzzy, etc. I came to be in some crackhead's abandoned, water-damaged basement, so I'm a little scaly.

The color of our skin is usually just the main color of our object but darker, but uncommonly, it can be other colors, I guess.
