Zenimax Media, parent company of Skyrim developer Bethesda Softworks, has filed a trademark for "Hearth Fire," the latest in a stream of applications related to the game. Fusible picked up on the trademark, which is a reference to a conjuration skill book and part of the "2920" book series found in the lands of Skyrim. Feel free to read the book on the Unofficial Elder Scrolls wiki.
Other trademarks recently filed by the company include last month's "Dragonborn" and April's "FUS RO DAH." The first... yes, the first... piece of Skyrim DLC, "Dawnguard," will be detailed next week at the industry's mega E3 trade show.
