I'd say the WORLD of DA is Dark Fantasy, the game isn't, because, well, gameplay. Lots of stuff in the original game just didn't have the opportunity to be explored in the depth that would really have lent that flavour to it.
The elves - Frantically clinging to the tatters of a lost legacy, forced to wander the wilds, abandoned by their gods, or living as third-class citizens in the slums of human cities.
The Chantry - Abandoned by their God, flat out admitting that their prayers are little more than platitudes and all they can hope for is a slightly less shitty afterlife than the heathens.
Mages - Pursued by demons, ostracised by society, and treated as perverse and criminal from birth.
Ferelden - Ruled by an impotent king at the suffering of feuding nobles.
Lyrium - This deserves its own spot because of what BioWare originally planned to do with it. Lyrium is mind-altering, addictive, toxic, caustic, and completely necessary to the continued existance of both Mage and Templar. Lyrium addiction was originally supposed to be just as damaging as the Taint, with an addiction mechanic severely penalizing mages and templars who did not keep taking it regularly.
Darkspawn - A living plague which corrupts everything it contacts, even the awakened disciples are doomed to live apart from other races for fear of spreading their sickness. Those who do not die immediately become violent, necrophagic savages.
Broodmothers - 'nuff said.
Dragons/Old Gods - Beautiful, wise, powerful, and completely without conscience or remorse, glutting their hunger for months in preperation for clutching of instantly mindless and ravenous young.
The Fade - Even your dreams can kill you.
Andraste - The messiah who failed.
Funeral practices - Bodies are burned ostensibly in memory of Andraste... The real reason is so that demons can't posess your family's corpse...
Grey Wardens - The best, brightest, and most talented in the lands... Doomed to a life of nightmare and encroaching madness, endlessly drawn towards certain death in the deep roads, all for the questionable benefit of a temporary immunity to infection. Face it, Wardens are the corpse-cart carriers of DA.
Dwarves - Born into a life of neverending, hopeless war.
Not a thing of real light or beauty in the entire mythos, is there? Even the griffons are extinct.
