I think bethesda should create a dlc in which the elder scrolls was usd against the dwarves or snow elves in the past when they were in a battle and make them reappear in the future and further explain there story such as adding a prince snow elf or a dwarven king and the reason for there struggle and tell there story. And maybe some new secret castles which they once inhabited.

...How is it that so many people fail to see the big THE ELDER SCROLLS: ONLINE logo at the top and think that this is the Skyrim forum?

This is the TES:Online forum Also the dwarves are extinct. The last one was in Morrowind and who knows if he's still alive

For the sake of good taste, no, they should not.
