So my plan for my campaign is to give my players character sheets that they will be playing in the game and them not seeing until the time comes. Essentially my characters will be themselves but pulled into another dimension when they be different people and I do not want them to create their own as I am basing this on a game universe and want to keep that part a secret. Is there a way I can create character sheets as a DM then give them to players once the time comes?
