Back in September 2018, ZeniMax Media, Bethesda's parent company, applied to trademark Redfall.
What is known
The dispute between the companies ended peacefullysettlement. The details of the agreement between ZeniMax and The Book Breeze were kept secret, but they noted that fans would be happy with this decision. Even during the height of the dispute, the author of the books said that he wanted to reach an agreement with the company by providing a license, but was never able to contact the lawyers. It's possible that ZeniMax were more accommodating this time.
It is possible that the company simply bought the rights to the series. Falconera wrote on his Twitter page that he was pleased with the result of the deal, but also did not disclose details.
ZeniMax did not say why it fought for the tradebrand, but gamers associated the name with the announced The Elder Scrolls 6. Bethesda has already decided on the location and release date of the new game, although it has not told gamers about it. It is possible that the sixth part of the “elder scrolls” will be called The Elder Scrolls 6: Redfall. Fans believe that the game will take place in two regions - High Rock and Hammerfell, as the announcement trailer also hinted at.
