HUGE FAR SPOILERS!! Entity is a mind demon. It does not have a physical form, and needs a vessel to physically move. It tricks you into letting it into your mind by saying things such as "I will make you rich. I will make them love you.". It knows your fears and can manipulate you using those fears. It feeds on negativity. If you are positive, it will stay away most likely. When the vessel is alone, a third, blue eye appears on the vessels forehead, speaking to the vessel. Entity can manipulate the vessel into doing something, and, when the vessel is fully corrupted, that vessel becomes a pawn used to manipulate others. Entity's purpose is unknown. If one has a strong will or mind, then they can force Entity out. One can also defeat Entity in a dream. Entity have been around for thousands of years, and it is unknown if it can d!3. According to legend, it was originally a cat, but slowly became evil, and, when granted a wish, was turned into a mind demon.
