Practically a ghost haunting these lands, the perfect definition of a background character. 

No one seems to be able to remember their true name, so they are known by many nicknames. The most common one simply being Blue.

Blue is the nightmare of being forgotten, from the simple forgetting where you put something to the harrowing realization that you can't remember someone once important to you. Surprisingly this actually does not effect Blue's memory at all, they actually have an excellent memory! Though they do have a strange effect about them, see Blue themself is.... actually quite forgettable it seems. It's not that they're boring, it's just that some things like their name or their face seems to slip people's minds. Such a thing would feel tragic to others, but Blue seems almost unbothered by it. They humbly accept their situation and have even learned how to sometimes use it to their advantage. They enjoy observing, and with being able to slip so easily into the background, its quite easy to learn a lot of things about others. 

Blue comes off as quiet, patient, and carries a naturally sad or frightened expression. They can handle a lot without showing annoyance, but when push comes to shove they're perfectly capable of fighting back. Blue can be found exploring various different places, they usually try to stay in peaceful places but somehow often find themself in an abundant array of increasingly dangerous situations. They're somehow still doing okay despite some of the horrors they've run into.

Kingdom

An endless meadow coated in forget-me-nots, a gentle breeze passes through the area. The sun feels warm and soft, inviting, but when you look up you find no sky at all.

Instead the sky is a reflective surface, and despite how far away it is, you can clearly see your reflection in it, but everything around you is foggy. 

There is a cottage somewhere in this kingdom, it looks abandoned, the brick is cracked and vines grow up the walls, you can't see through any windows. The inside is clean and clearly lived in, it's insanely bigger on the inside. There are shelfs with little knickknacks dotted around the place. You notice a lot of mirrors and photos on the walls, but every mirror is fogged and every photo blurry.

Occasionally you think you hear something, it sounds familiar, but when you look around you find nothing at all.
