A survey has leaked ideas for a new $14.99 story-based Dragon Age: Inquisition downloadable content add-on.

BioWare said earlier this month that "we're not quite done with story content for DAI just yet", suggesting more would come.

The survey was received and separately verified by people on the Dragon Age forum and Reddit.

The survey talked about the DLC involving "the final fate of the Inquisition" and describes it as "a last adventure" as well as "your next mission". This suggests it is both the next piece of DLC and the final piece of story DLC. There has been one other story DLC in Jaws of Hakkon, which came out earlier this year.

The content of the new DLC revolves around confronting "the one who started it all" and about facing "a great evil before it is too late". Are these one and the same being - the being in the revelatory epilogue who I don't want to name for spoiler reasons? Let's hope so - it's a major loose end. Creative director Mike Laidlaw has already told us there is desire to pursue this discussion, but not end it, in future DAI content. Could the rest be saved for a future game?

Anyway, the full email blurb follows. It's titled, "Decide the final fate of the Inquisition as new threats emerge."

It reads: "Having saved the world of Thedas by closing the Breach, your next mission will determine the future of the Inquisition. Your mark suddenly glows, erupting with magic connected to the Fade. Assassins attack in shadow. An invasion of enemies begins. Win a race against time to face a great evil before it is too late. In this story-based expansion, playable after the events of Dragon Age: Inquisition, you will embark on a last adventure with your team to confront the one who started it all."

A bullet-point list of features adds:

"Test your mettle against the full force of the disciplined and battle-hardened Qunari army"

"Explore diverse, new areas as you fight the threat across the whole of Thedas"

"Uncover secrets of the Fade that will change your understanding of the world as you know it"

"Prove your skill with a new, optional gameplay mode that challenges even the most seasoned veteran"

Where did a Qunari army come from? Is that a harder difficulty mode or some kind of wave-based mode? Are those secrets of the Fade related to the Inquisitor's mark? Explore the "whole of Thedas" - as in, beyond Orlais and Ferelden, the kingdoms in DAI? The Dragon Age: Inquisition forum members discuss all this - and have some great ideas along the way.

Note, the features mentioned above may not be nailed down but represent EA testing various ideas out. One or more could be omitted from whatever DLC finally arrives.

What isn't mentioned is the Deep Roads area that BioWare had teased we may get to explore. The Deep Roads area was in both Dragon Age 2 and Dragon Age: Origins. It's a vast underground network of roads built by an old dwarven empire.

It's also not clear whether new story DLC will fall under the same exclusivity deal as Jaws of Hakkon, which appeared on PC and Xbox One first in March - and then on PC, PS4 and Xbox 360 in May. It cost £11.99. Here's our review.

Inquisition has had minor add-ons in the shape of the paid Spoils of Avarr item pack, the free Black Emporium shop, and some extra promotional items released around launch. There have been two multiplayer DLC add-ons, Destruction and Dragonslayer, added since launch.
