The Arboretum is the southeastern district of the Imperial City. It has an armory where a unique set can be crafted.
Each Alliance has a rally point along the outer wall of the Arboretum which can be accessed from their Alliance Base in the Imperial Sewers. The rally points are protected areas which members of enemy alliances cannot access, but enemy players can still attack players at the rally point from below with ranged weapons and spells. There is a Sanctuary area in the immediate vicinity of the rally point trap-door which nullifies all damage while a player is standing in it.

The Arboretum Sewer Entrance is located near the northern end of the district, along the outer wall. It provides access to the Irrigation Tunnels section of the Imperial Sewers.
