The creators behind The Elder Scrolls V: Skyrim may be plotting something big for their fans. The widely received follow up to Oblivion could be seeing a new downloadable content expansion in the near future.

Bethesda parent company ZeniMax just filed a trademark for Dawnguard, according to ComputerAndVideoGames.com. Dawn Guards are characters that appear in Oblivion, and are members of the game's Mythic Dawn cult.

The trademark filed is for computer game software and video game consoles; downloadable computer game software offered via the Internet and wireless devices. It's possible that the patent could be for a new title, but speculations point towards a more Skyrim content.

A post on a GameFaqs forum said that Bethesda has decided to release three massive DLC along with some minor add ons. The first will be called Riders of Hammerfell, in which players will begin a new quest line involving a guild called Dragon Riders. Characters will also obtain the ability to fight with magic, shouts, and other powers on mounts.

The second, called the Morrowind DLC, involves a werewolf quest line and other animal transformations. The last expansion is a war with the Thalmor taking place somewhere in Cyrodil. However, this has yet to be officially confirmed or announced and could be speculation at this point.

Last month Todd Howard of Bethesda dropped some clues indicating a Skyrim DLC during Game Jam, a week-long event allowing developers to showcase their upcoming works. The Bethesda employee teased fans by throwing out possibilities without actually confirming them.

How much of this stuff sees the light of day? To be determined, Howard said at the event when referring to the work displayed. Could it be in a future DLC? We don't know. Could various parts of it just be released for free? We don't know.

About a week ago some of the features Howard mentioned became a reality for Skyrim fans. Cinematic kill cams for projectile weapons made their way into the PC update of the game.

This could mean that new DLC will be in store for Skyrim fans sometime soon, especially since there is a new trademark to back it up. At least, players certainly hope so.

Y'know what would go really good with all those new kill cams and kill animations in Skyrim? An expansion pack and new quest DLC, a fan posted on Twitter.

Getting the last couple of achievements in Skyrim, then I am done with you...until the new DLC of course! posted another.
