Fate Bound - The player is from the start going to experience through the story and the setting that they are destined to save the world. But not in the typical bright railroaded way, instead they are to choose their own way of dealing with fate. For example making deals with the equivalent to the Devil in order to save the world. But it’s a continous tug of war with fate where the Fate Bound path involves sacrifices.
Mystical - There are a lot of mysterious things happening throughout the game, unhuman creatures lurking, time being bent, curses placed and protection spells being used.
Nordic - Not a primary experience but still important for the thematic setting. Everything should feel nordic, not Viking Nordic but more to the Sami or Medieval Swedish settings.
