Ma'adim Subterrane

Ma'adim Subterrane is a Lost Sector on Mars, in caves on the eastern side of the Glacial Drift in the Hellas Basin, first appearing with Destiny 2: Warmind. Fast travel to Glacial Drift and turn around; the entrance is in a nearby cave wall. A hidden chest sits in the bush to the right just before the entrance.

Enemies

Cabal including Legionaries, Centurions, Psions, War Beasts, Gladiators and Phalanxes. The boss is Valus Dulurc, a Colossus. Use your Super or rockets from range, then open the chest beside him.

Lore

The subterrane was previously held by Red Legion deserters under Valus Dulurc and is the crash site of Uldren Sov's starfighter after the Battle of Saturn. Before Destiny 2: Forsaken, its placement in the lore was inconsistent. "Ma'adim" is Hebrew for Mars.
