By owning the Imperial City DLC or being a member of ESO Plus, players may enter the Imperial City Sewers through three gates in the middle of Cyrodiil. No matter which gate is entered, you are led directly to your alliance’s base, where more quests and Merchants are found.
There are six districts of the Imperial City: Arboretum, Arena, Elven Gardens, Memorial, Nobles, and Temple. The city is open PvP, with quests available in each district once the Imperial City story quests are complete.
