Vessels



Vessels, or Meatsuits, are organisms who serve as the physical body or imbodiment of spiritual, non-physical beings.

Characteristics
Angels use vessels as a means to physically interact on Earth. Angels require a vessel to manifest safely outside of Heaven. T he spiritual physiques of angels are too intense to behold and can be catastrophically damaging to most people, with the exception of the angels' own vessels.

Angels must have the permission of their host to indwell them. This is different from demons, who force themselves upon a host and do not need a particular vessel.

Angels have multiple people that can be vessels for them, but only one person is their "true" vessel. While in a lesser vessel, an Angel's abilities are limited when compared with their true vessel, and, as evidenced by Lucifer, may be damaging to the human. Archangels require their true vessel, otherwise they will burn out the body they are inhabiting.

Process
It is law that angels use vessels to interact within the physical world. But in order for this to happen, the Angel must first gain consent of their would-be vessel, who must voluntarily agree to the transaction, and no angel can disobey it, and thus will only take a willing vessel and will not and can not force themselves into a human like demons, thanks to the laws of God. Even Archangels aren't exempt from this. Because of that, and the fact that most humans cannot stand the sight of an angel's true form the angels have to find willing vessels. After finding a potential host, the angel will then communicate with the human through visions in order to explain themselves and ask for the human's consent to gain control of their body. Such as when Castiel contacted Jimmy through his household electronics and showed him vision of what was to come. However, Lucifer tormented his vessel in order to get his consent through psychological hallucinations. Angels who have manifested within a vessel have superhuman abilities that easily surpass the power of a demon. It is unknown whether angels supress their hosts like demons, but Jimmy described having Castiel inside him like being "strapped to a comet".

Archangels however are much more powerful than regular angels and as a result their presence in a human "hollows them out" leaving a vacant empty shell once they leave the human with recovery unknown.

Angels can leave the host whenever they want to or if they are called away by the higher ups, leaving the vessel with little or no memory of the time they were occupied. The process also doesn't kill the human either. Also, as angels do not need to eat, a vessel may find themselves extremely hungry after being freed from posession.
