Relics are objects imbued with the soul/ spirit of a being whether it be animals, people or elements that correlate with something.

Relics are essentially prisons to most spirits if and only if they are forcibly placed into an object

Because of this the soul in question only accepts its user after they have been through a traumatic experience , if the relics power is obtained through force although powerful the relic cant be used to its full capacity, if the relic senses it's master is weak it will take the opportunity to obtain a physical form by overpowering their soul and possessing their body.
