Y/N is a very special character within the story because they are the sole survivor of the Marta, a scientific research vessel that was destroyed in a catastrophic explosion. The Marta was known for carrying scientists and researchers who worked on dangerous experiments deep in space, making its destruction even more mysterious and tragic. While everyone else aboard the ship was lost in the blast, Y/N somehow managed to survive, something that should have been impossible. Because of this, they are seen as both extraordinary and deeply mysterious, with their survival setting them apart from every other member of the crew. With that, they have some deformities from that radioactive blast (can be anything u choose)
