From the wiki:
The Dalish elves and city elves in particular have a strange and bitter relationship, dating from the splitting of the People after the fall of the Dales. Some Dalish view their city brethren suspiciously and with pity as "flat-ears,"[17] culturally human elves who are no different "than their shemlen masters."[19] To some, they are seen as having given up on and forgotten their culture, and the hope is to teach these elves their past when a new homeland is founded.[20] Not all Dalish share this view of the city elves, however.
On the other hand, some city elves see the Dalish as near-myths: strange and savage "wood elves"[21] living far from humans and preying upon the unwary;[22] and yet somehow noble, as well.[23] To others, the Dalish are seen as "savages", primitive elves who refuse to see the promise of the alienage, and live off the land in ways the average city elf could not.[24] Indeed, city elves who choose to leave or live beyond the Alienage are labeled "flat-ears" as well by their city kin[17], ironically similar to how some Dalish view the Andrastian elves, and subject to violence or resentment from other city elves.
And yet, for all this uncertainty, city and Dalish elves still interact positively now and then. For Alienage elves who seek to leave their home due to desperation, poverty or abuse, wandering Dalish clans are often seen as a sort of "last resort" haven. They are normally willing to take in a refugee from the cities and to largely refrain from attacking a city elf on the road[25], despite their uncertainty, and train them in the ways of their Creators and culture.[26] Similarly, Alienages may take in a Dalish elf who has broken with their clan voluntarily or involuntarily.[27]
Elven mages tend to be grouped to the Dalish mindset along with city elves.[28] This is particularly the case as they have turned not only their lives but their magic over to the human Chantry andMaker, and the Circle of Magi, with the Circles being implied to have played a role in the fall of the Dales.
