Although it took more than a year for Bethesda Softworks LLC to launch the first downloadable content for The Elder Scrolls V: Skyrim, it appears subsequent expansions are rolling out every couple of months.

In December, Skyrim players were introduced to the most recent DLC offering, Dragonborn, and now Bethesda may be planning another game-play addition.

Last month, Bethesda’s parent ZeniMax Media Inc. filed to trademark the term Redguard, according to Xbox 360: The Official Xbox Magazine. While there has been no official confirmation that new Skyrim DLC is in development, the trademark ownership applies to “downloadable computer game software offered via the Internet and wireless devices.”

Some may object that this is merely a move to mark territory and prevent other companies from using an Elder Scrolls staple term, but ZeniMax has been known to file for trademarks specifically relating to new DLC releases.

Long before Dawnguard, the first Skyrim DLC, made its debut, ZeniMax claimed legal ownership of the term. This is a pattern that has persisted with Hearthfire and Dragonborn as well, and each filing came with the same “downloadable computer software game” description.

Pete Hines, Bethesda’s vice president of marketing and public relations, refused to comment on the matter. Hines has come to be known as an intermediary between Bethesda and Skyrim players when it comes to DLC launches, and he has actively responded to fan queries via Twitter in the past. This time, however, he had no information to share on a potential Redguard expansion.

“Sorry, I don’t comment on every rumor that comes up,” Hines tweeted Jan. 3.

If this rumor turns out to be true and Redguard is in fact the next Skyrim DLC, players could be returning to the province of Hammerfell. Redguards are known as the most naturally talented warriors in all of Tamriel, descended from a long line of warriors and mystic seers.

According to The Elder Scrolls Wiki, Redguards are more proficient with the use of weaponry than any other race. Of course, it’s too soon to know what a Redguard DLC would entail, but, based on what is known about the race, players could expect a heavy emphasis on combat. Players have dealt with battling blood-thirsty vampires and the first Dragonborn, but the Redguards are legendary experts when it comes to battle.

While Bethesda may be plotting its fourth Skyrim DLC, PlayStation 3 players have yet to experience any of the previously released expansions. Bethesda has admitted to encountering technical difficulties when it comes to developing Skyrim DLC for Sony’s video-game console, but the company recently announced that the Dragonborn DLC will launch in a few days.

“This is not a Dawngaurd issue,” Hines tweeted back in October in reference to Skyrim DLC for the PS3. “This is a DLC on PS3 issue. It affected DG because it was the first one.”

Dragonborn will make its debut on the PS3 on Feb. 5, and the other two previously released Skyrim DLC offerings are also expected to launch on the console this month. Bethesda has not specified a release date for either Dawnguard or Hearthfire, but it did promise that each would be available sometime during February.

There’s no telling what we can expect in forthcoming Skyrim expansions, but a video from the DICE (Design, Innovate, Communicate, Entertain) Summit last year could provide some insight. The developers of the game got together and created a montage of ideal features they would like to see in it.

Some of these additions have made their way into the currently available Skyrim DLC packages, such as dragon mounts, which were introduced in Dragonborn, and the ability to adopt children, which made its debut in Hearthfire. Check out the video below to see for yourself.
