Astral perception or supernatural perception is the ability to perceive what would normally be invisible to humans such as ghosts and reapers. Certain monsters are normally invisible to humans unless they wish to be seen. Some magical sigils are also invisible to humans. Angels can see the true faces of demons in a vessel, and demons can tell if a human is possessed by an angel and can see hellhounds without Hellhound Glasses. Other supernatural beings like deities and fairies possess astral perception as well.
It is possible for humans to gain the ability to see Fairies, and thus a limited form of astral perception, by going to Avalon.
