Are there any unicorns/dwarves in Skyrim?

Are there any unicorns in The Elder Scrolls V: Skyrim? In The Elder Scrolls IV: Oblivion I have found unicorns. But I don't know if they exist in Skyrim.

Also, there are rumours about dwarves in the game. But has anyone seen any?

Solution 1:

Dwarves (or Dwemer) in Skyrim have been "extinct" for a long time, the only remains of them are their ruins and automatons. http://www.uesp.net/wiki/Lore:Dwemer

I'm not sure about Unicorns, but I haven't seen any yet.

And there is nothing on the wiki: http://www.uesp.net/wiki/Lore:Unicorn#Unicorn

Solution 2:

As far as the Dwarfs (or Dwemer) are concerned: they are an extinct species of elf, whose names mostly end in -mer:

• Aldmer (a.k.a. Elder Folk)
• Altmer (a.k.a. High Elves)
• Ayleid (a.k.a. Wild Elves, Heartland High Elves)
• Bosmer (a.k.a. Wood Elves)
• Chimer (a.k.a. Changed Folk)
• Dunmer (a.k.a. Dark Elves)
• Dwemer (a.k.a. Dwarves, or Deep Folk)
• Falmer (a.k.a. Snow Elves)
• Maormer (a.k.a. Sea Elves or Tropical Elves)
• Orc (a.k.a. Orsimer, or Pariah Folk)

(List lifted directly from the UESP page on Races)

Please note that as direct descendants of the Aldmeri-Nedic Manmer, Bretons are sometimes known by that name: Manmer.

The only thing left of the Dwemer as far as I know are the ruins of their cities and some of their mechanical creations.

I don't believe there is a unicorn in Skyrim.
