It is said that those who hear Occulus, die immediately. He was the guardian of dreams, but something else took over his position.
Occulus is a corrupted guardian, meaning that it is very difficult to return to his normal state.
Occulus has many eyes, and when all of his eyes look at someone, he shares his pain with them.
Guardians can be followers if they have protected what they needed to protect for long enough. Although, it is possible for another to take over whatever they're protecting which can lead a guardian to becoming a forgotten one.
A forgotten one is a creature that used to be a guardian, but is becoming more and more corrupt, and damaged in their appearance and emotion.
The more corrupt a forgotten one becomes, the closer it is to becoming a Deathmarker.
Deathmarkers are able to send death, or even cause death anywhere they go. Deathmarkers are the opposite of guardians, they destroy anything in their way.
