Kotaku has the background...
BioWare has been hooking up players with non-player character party members in its games for more than a decade, but there's not been a strictly male-seeking-male option available until Dragon Age Inquisition's Dorian.
Polygon has the new developments...
The Dragon Age series is getting its first exclusively gay male character, which will also be the first fully gay male party member for BioWare as a whole, series writer David Gaider revealed in a post on the official Dragon Age Inquisition website.
DragonAge.com has a more in-depth character profile...
In Tevinter, mages form the ruling class. He comes from a wealthy and influential family, one of many that arrange marriages and raise their children to become perfect mages… yet Dorian has rejected that life. He's seen the corruption to which it leads, and he refuses to play along despite the fact it's made him something of a pariah.
PinkNews provides more context...
Dorian, on the other hand, is a character that gamers can play as or can choose to have a romantic and sexual relationship with, if they play as another male character.
The game’s writer David Gaider said: “It added an interesting dimension to his back story, considering he comes from a place where “perfection” is the face that every mage puts on and anything that smacks of deviancy is shameful and meant to be hidden.”
