Writer's Fallout Shelter

Thanks for sharing the link ~ I too thought it referred to a character's name, but now it appears that it's a character type? Not knowing the work to which you refer, however, is it manga or anime-based? Then the "Mary Sue" might be an appropriate type of character?

Also, since you are still writing the story, the character has yet to develop fully and flaws or peculiarities may crop up as she grows with the story, to where she becomes a canon character? Her life and growth is in your hands ~

Keep Writing!
