In the Deep
From Destinypedia, the Destiny wiki
In the Deep is the second story mission of the Shadowkeep Campaign and the thirty-seventh Story mission of Destiny 2. Eris Morn needs a Hive artifact deep within the Hellmouth. The Guardian is tasked to find it and bring it back to her.
Upon reaching the entrance, The Guardian is greeted by flights of stairs, descending into the dark.
After sometime, journeying ever further into the depths.
Continuing on, The Guardian eventually reaches a chasm flanked by the colossal Pyramid.
Activating a nearby sigil, a bridge is created and The Guardian begins to cross it.
Upon crossing the bridge and up a small incline, the Cryptoglyph comes into sight.
Hive forces begin to spawn in and attack The Guardian, with wizards creating an energy field around the Cryptoglyph in defense. After eliminating all nearby Hive, The Guardian retrieves the Cryptoglyph.
The Guardian is suddenly drained of Light. The chasm goes dark.
Lightless and surrounded, The Guardian makes a mad dash for the exit, eventually reaching the surface.'
