Not a ghost, but a lost entity

Idk, I just got an idea about new character (maybe) 

So this is Nebula. It´s really peaceful and lovely creature. It´s has no genre so, be careful with to talk to him/her. It´s can floats like a ghost or it can to create parts of body (so it can create a legs). It´s almost never show his/her face and don´t even try it to stole his/her hood, it will be very mad >:C
