Meanwhile, its story will chronicle what happened to Thedas' last Inquisitor:
"Discover the fate of the last Inquisitor and the powerful dragon he hunted. Enter an overgrown wilderness filled with Avvar, fiercely independent hunters who settled in the southern mountains of Thedas.
"Explore their culture to uncover what happened to the last Inquisitor and the dragon he pursued. Find an ancient Tevinter fortress that hides a dangerous secret. In this new adventure, playable within the Dragon Age: Inquisition campaign, you will face powerful foes, gain legendary armour and weapons, and confront an ancient god of war bent on destroying the world."

ORIGINAL STORY 23/03/2015 4.51pm: A set of leaked Dragon Age: Inquisition achievements has revealed our first look at a new single-player DLC.
The untitled expansion has yet to be announced by BioWare, but the achievement images and descriptions hint at what the add-on will include.
Four achievements are unlockable in the new DLC (thanks, Xbox Achievements).
The first award, Firestarter (15G), is awarded for destroying all Winter Shards and lighting all fires in a new location, the "Old Temple".
The next, Legend-Marked (30G), is awarded when you impress the Avvar tribe of Stone-Bear Hold and gain their friendship. The human Avvar have already made an appearance in Inquisition, although their influence was fairly minor.
Players were previously asked to impress a Dalish clan in what may be a similar fashion - via completing side-quests and missions to rank up influence.
The third award, Historian (30G), hints at you uncovering secrets of a "legendary figure". An elf is shown in the imagery.
And the final award, Winter's End (90G), is awarded when you "dispel a myth of ancient days".
Speaking to Eurogamer earlier this month, Dragon Age: Inquisition creative director Mike Laidlaw hinted that the game's first single-player add-on would be revealed in the not-too-distant future.
Laidlaw said that he was aware that fans wanted new areas to explore, but also a story continuation for the game's post-credits scene.
"The two big pulls are - 'I want more of this game' and 'I've reached the ending and I want to know more about the characters, or one specific character'," Laidlaw teased.
"I don't want to go into too much detail but I'm well aware of both of those camps and I'd like to see both of those groups satisfied before we're done."
