Recent demographic data estimates that there are now more than ten million people (I hesitate to write "sapient beings" because I don't want to assume) on Mundus. While the majority of those is of little concern for us, the gods in their wisdom have decided to celebrate and give everyone the opportunity to win one of 300 prices.

You can participate as follows:
If you'd like to be one of the 300 lucky winners, follow the steps below:
Register for the 10 Million Stories Sweepstakes via the online entry form.
Play The Elder Scrolls Online any time between November 1, 2017 at 12:01AM EDT, and December 6, 2017 at 11:59PM EST.
(Alternatively, you can enter by sending the Mail-In Entry Form between November 1, 2017 and December 6, 2017.)
Apparently you can do things to increase your chances:
Want to increase your chance to win? Keep an eye out for a future in-game dungeon event that'll help you earn bonus entries. We're also giving everybody an opportunity to play ESO with a series of Free Play events, starting with the Xbox One tomorrow! You can find more information on our Free Play page. If you're on PS4 and PC/Mac, keep an eye out for an announcement in the coming weeks.
According to the rules, you can gain up to 7 bonus entries to a total number of 8 by completing a random dungeon or veteran dungeon from the dungeon finder once a day between 10 am EST 30.11. 2017 and 09:59 am EST on 06.12. 2017.
Please note that you can only earn one ticket every day, and not more than one on any given day.
