The Umbra appeared in the episode "The Tale of Bigfoot Ridge", it was mostly portrayed Sarah Edmondson.
BiographyAn Umbra is a Shadow Ghost or a Darkness Ghost who cannot stand light. The more light it is exposed to, the more damage it takes. They occupy an area where the light is dense or completely dark. Then they will lure ita victims to where they are. They usually do it by by casting an illusion of a person they know asking for their help. Or someone in general asking for the victim for their help.
Then once they have lure the victim inside, they track them down to where there is no light; then they prey on them. They gleam their glowing eyes at them and stare at them until they transform into them. When this happens, they gradually feed off of their victims lifeforce.
Then time it takes to kill off their victim varies. The less light there is, the faster it takes. The more light the victim stays around, the longer it will take. When it approaches they victim in a dark area, they will begin to slowly drain more of the victims' lifeforce by repeatedly staring at them with their gleaming eyes. When they do this, their victim begin aging rapidly.
The Umbra eventually needs another victim, when their current victim has died or is close to dying. Therefore they lure another victim to come to where they. They can do this by making sounds and casting illusions. Which is usually of a person they know to trick them into showing up. They can be slowed down, if the victim stays near areas with light in them. Also by shinning bright objects at them such as flashlights, lanterns or torches. However this isn't enough to defeat them. They need to be exposed to full complete light, such as the sunshine outside. Or a room filled full of turned on lights. When this happens it will cause them to be obliterated and destroyed.
