I need insights quickly on lost sigil

What happens if another witch finds one of my demonic charged sigils. It has no blood binding. Can it be used by someone else? Or the chosen entity will attack the person who found it?

What are your insights on that?

PS most of them have no names attached only the sigil with the circle, the symbol of the Mother of Chaos Leviathan, the Dragon of the Void


What would you do if you found a daemonic sigil? I guess all depends on the practitioner will that witch even be aware it’s daemonic? Or maybe the demon made you loose it on purpose so it would get to this witch…
