@killiansmith1 Sorry, having a little trouble understanding the problem... Are you missing a hero/character (warden or Hawke) from one of the previous Dragon Age games in your Keep, or has your playthrough state from one of your playthroughs from Inquisition gone missing? Or are you missing a tapestry you created in the Keep?
You don't create Heroes/characters in the Keep, you create world states (basically the decisions from DAO and DA2) to be imported to Inquisition when you start a new game. Once you've started a game with a world state, you can't alter the world state for that playthrough.
