Arboretum

Sector Notes:

Enemy Clusters: Hive: 1

Material Nodes: Available

Partially Inaccessible

Scannable Objects: 3

Strike Mission: Savathûn’s Song

The main mezzanines and vast hallways showing the plant life that could grow on Titan have been left to fester. Now the Hive forces have spread through these hallways like a virus. Accessed from Solarium, most of this Sector (aside from some initial hallways) is inaccessible unless the Strike: Savathûn’s Song is active. Should this occur, you have a massive number of Hive foes to tackle, including Wizards and Ogres, as you battle through the various chambers of Arboretum, destroying strange Hive crystals as you go. Only then can you drop down into the Chasm of Screams, where you face the biggest Hive foe. Under normal conditions, spend time here locating scannable objects and honing your Hive-culling talents. Note that one of the locations (the Reactor Core) is only available during the World Quest: Enemy of My Enemy.

Areas of Interest

Exit to Solarium (North)

Several smooth-floored and relatively clean corridors are accessible should you venture here from the Solarium. A scattering of Hive foes and a scannable object are likely in this area.

Main Hall

A long and impressive main hallway with a giant pink-colored LED wall visible as you arrive and look left (south). Look out, as the place is teeming with Hive (even more so during the Strike). Come here to clear the area, and progress no farther if the Strike is active.

The Pit to Chasm of Screams (Inaccessible)

This is inaccessible unless the Strike is active. This is the central hub to the lower expansive part of this Sector. The only way to reach the Chasm of Screams (during the Strike) is by destroying the chained crystal. Note the north and south Hive tunnels and the main corridor to the east.

Bio Dome Mezzanine (Inaccessible)

This is inaccessible unless the Strike is active. This huge, impressive series of open-air platforms is filled with Hive foes during the Strike.

Crystal Chamber (Inaccessible)

This is inaccessible unless the Strike is active. Accessed after negotiating your way through the Bio Dome Mezzanine, this dead-end platform is bathed in reddish light, with a large crystal at one end. As always, plenty of Hive are here.

Interior Mezzanine Entrance (Inaccessible)

This is inaccessible unless the Strike is active. Enter the area after maneuvering through the Hive tunnel on the south side of the Pit.

Lower Mezzanine Entrance (Inaccessible)

This is inaccessible unless the Strike is active. After fighting the Hive across the Interior Mezzanine, there’s a lower area connected to the Main Corridors. Once again, Hive foes are plentiful.

Main Corridors (Inaccessible)

This is inaccessible unless the Strike is active. A large L-shaped corridor section leads from the Lower Mezzanine back to the Pit. Note that the reactor room to the east is inaccessible, even during the Strike.

Reactor Core (Inaccessible)

This is inaccessible unless the World Quest is active. Reaching this reactor chamber is the culmination of the World Quest on Titan. Face down a Fallen Captain, and complete the mission. This is the only time this chamber is accessible.

Scannable Objects

Strikes

Savathûn’s Song

Almost the entirety of Arboretum opens up during this Strike. You’ll encounter a huge number of Hive foes, including Wizards and Ogres, which are simply a prelude to the really nasty foes deeper down in the Chasm of Screams!
