This is the form I would take if I appear in the story at any point.

Origin AU: Outertale

Appearance: A 5.4 ft tall lavender coloured Napstablook like ghost that's lower body moves with a airy dress like affect, she has three small eyelashes at the outer corner of her white eyes and wears a shear lighter purple, star print veil that is somehow held in place by a bright blue echo flower on the right side of her head. Carries a white messenger bag that is also a unlimited dimensional box who knows what's in there but her.

Personality: She is a forgiving but forgetful and has been compared to Ink Sans in the memory department as she does have to sometime write down what she needs to remember in a large book she keeps in her bag with her favourite fountain pen, thankfully this does not happen THAT often. she can be a little mysterious with the way she seems to be everywhere listening to what is going on and offering her own thoughts and ideas, can be a bit blunt when needed but otherwise is normally polite.

History: Lived quietly drifting through life in Outertale collecting lots of odds and ends, stockpiling things she thinks she might need, occasionally stopping to draw the scenery in a random sketch pad she has in her bag. Her attacks are in the form of anything she grabs out of her bag to throw at the enemy this can include things like darts, marbles, pencils, food and tissues. (I did say that only she knows what is exactly in that bag, it does not help that's it is an unlimited dimensional box she somehow found or is it made?) Uses Green and Purple SOUL Magic.

(A ghost monster would probably have their own form of magic? Like for example Skeletons have eye lights and how their bones stay together. so a ghost would probably be able to pick things up without touching like a lesser form of Blue SOUL magic (I think...Why did I write this?))
