People who have subscribed to The Elder Scrolls Online for a long period of time will be rewarded in the game's new loyalty program, according to Bethesda. The loyalty program will provide long-term users with different rewards, with the first being a High Hrothgar Wraith vanity pet. That reward will be sent out automatically in September to anyone who has paid for three months of service.
The subscription to The Elder Scrolls Online does not have to be continuous, only combined. So, if you took a month off from playing the game, then you can still receive the reward once you reach three months of subscription service.
