Elder Scrolls Online's yearlong Season of the Dragon has kicked off starting today with the release of the Wrathstone DLC and Update 21. Players will find a pair of new dungeons: Depths of Malatar and Frostvault, both of which lead up to the Elsweyr content expansion coming on June 4th. "Each dungeon holds one-half of the ancient Wrathstone tablet, the key that Abnur Tharn later uses to open the Halls of Colossus, accidentally unleashing the dragons upon Elsweyr".
The Wrathstone DLC is part of ESO Plus membership or it can be purchased separately in the Crown Store.
In addition to the Wrathstone DLC, all players will receive Update 21 that includes a number of QoL improvements and a new Battlegrounds map, Passive Ability updates, a Guild Trader update and the Zone Guide system.
