Bethesda's parent company ZeniMax has trademarked the term "Dragonborn" in what could - whisper it - be a clue as to the second Elder Scrolls 5: Skyrim DLC pack.
Taken out on 18th May, the filing is limited to "computer game software for use with computers and video game consoles; downloadable computer game software offered via the internet and wireless devices".
Beyond the presence of bearded men with glowing eyes, little is known about Dawnguard's contents. We have our suspicions - the pack could involve the return of a Daedra-worshipper faction from The Elder Scrolls 4: Oblivion, though one Skyrim update points to a Snow Elf invasion and the introduction of crossbows. It's possible, of course, that certain rumoured Dawnguard content may show up in a subsequent Skyrim DLC pack.
Sounds fairly cut and dried, doesn't it? Keep those eyebrows raised - Zenimax recently sent a legal warning to the creator of iOS app Dragon Shout, complaining that it violates an unspecified trademark. "Dragonborn" may well be a smartphone spin-off of some kind. Or, as OXM Twitter follower nibblemonkey argues, the trademark could just be ZeniMax (over-)protecting its IP.
As ever, let us know your thoughts. Look out for more on Dawnguard at E3.
