The game will feature five areas: Ferelden, The Free Marches, Orlais, Nevarra and the Dales. The last three of these places have only been talked in previous games. Players will remember that Dragon Age: Origins took place in Ferelden while Dragon Age II took place in the Free Marches.
Your actions in these areas will have significant repercussions. You can “affect environmental changes to drastically influence local settlements, establish trade routes, capture territory and disrupt the local ecosystem.” Hunting a particular animal or harvesting a specific species of plant can lead to their scarcity and allow other species to become dominant. Killing specific groups of enemies in an area or dragons will also impact a region.

Your character will be the Inquisitor and like DAO, you will be able to choose what gender they are as well as their species. The character will have a total of four voices (two male and two female). The reason given for why there weren’t a total of eight voices is due to hardware limitations (presumably of the last-gen consoles). Each player’s origin will play out more or less the same as it is tied directly into the main overarching plot of the game. The player will have the unique ability to close rifts from The Fade that have opened up throughout Thedas.

Lastly, the game will feature 40 different endings. These endings are influenced by actions taken during the course of the story. The endings are said to be significantly different from one another and won’t just feature minor variations.
