I noticed they have an Australian accent. Reasons for this actually make sense.
The population of Australia is descended from British convicts, much like the Dunmer are descendents of a race of mer that was punished by the daedric prince Azura.
The Australia is a large island continent, much like how Vvardenfell is a very large island.
With these two points, does it seem that the Dunmer accent was inspired by these two facts, or am I just mad like the Wabbajack?
Lol it's not an Australian accent, it's just a bad attempt at a London accent. We call it a "dike Van Dyke" Basically when an American tries to do a Brit accent and fails, and ends up sounding like dike Van Dyke. The female version is known as a Mary Poppins.
Btw no races in the game seem to have a set accent, like they did in Oblivion. Some of the Dark Elves have an American accent, same goes for Nords. Some of the Nords sound Scandinavian. Imperial and Redguard also have a lot of mixed accents.
