The Dragon Age Keep app (Origin account required) and a good internet connection are necessary to change the world state; there is no in-game checklist/import feature. Inquisition can be played without Keep using the single default world state.
PS4 account and Dragon Age keep accounts may need to use the same email to work.
A massive explosion destroys the Conclave and creates a hole in the Veil — the metaphysical boundary between the physical world and the Fade, the world of spirits and demons — referred to as the "Breach". The only survivor of the blast is the player character, who emerges with a mark on their hand capable of closing rifts in the Veil that have sprung up in the Breach's wake, but who retains no memory of what happened. Witnesses claim the player character was ushered out of the Fade by a mysterious female figure, rumored to be the prophet Andraste, the historical Bride of the Maker.
At the beginning of the game, the player chooses a race for their player character: human, dwarf, elf, or Qunari, a playable race for the first time in the series. Players customize the Inquisitor's physical appearance and gender, among other things. The game has a semi-open world structure, as the world is broken up into several sections, which players can freely explore. To allow players to navigate the game's world faster, mounts, creatures players can ride, are introduced.
