The title should really be Hammerfell.

It just slaps. It's unique to TES and definitely NOT generic like Sentinel or Dominion. It's interesting. It's 100 percent a kind of title that will be used as shorthand such as Skyrim is. "Hey I'm gonna go play Hammerfell" is so much more unique than "Hey I'm gonna go play Sentinel."

Morrowind, Oblivion, Skyrim, Hammerfell. It just works.
