https://www.pcgamer.com/morrowind-is-free-for-the-day-to-mark-the-elder-scrolls-25th-anniversary/ > The Elder Scrolls: Arena is 25 years old today, and to celebrate the big birthday Bethesda is giving away The Elder Scrolls 3: Morrowind. Just pop over to bethesda.net, log in to the site (or sign up if you need to) and then—wait!—do not hit the "Redeem Now" button yet! > I know, that seems like the obvious thing to do but first you want to take note of, or perhaps even select and copy, the "TES25TH-MORROWIND" code, without the quotes. Now hit the redemption button, put the code into the field, click where you're told, and the game will be added to your account, accessible through the Bethesda launcher.
