Step 6 - Investigate the Wall
Talk to Rookie (sp_rudus 193/284) located directly south of Elena. He says progress is blocked by a large 3-layer door and needs help investigating it. He tasks you to investigate around the wall for other means of entry. Visit all three yellow markers: Wall on the Railroad - Rebellion Member (sp_rudus 304/266) to the East, who deduces the wall was built after the refinery was no longer under operation. Watchtower - Rebellion Member (sp_rudus 121/286) to the West, who says the pillar beside the wall was actually a watchtower and noticed lots of movement on the other side. Small Hole (sp_rudus 27/300) along the western edge, which looks like it was made by a small animal.
Step 7 - Report and Door
Report the findings back to Rookie. He was able to unlock the door but discovered it was designed with a weird mechanism: someone has to keep holding the button to keep it open. The odd design was probably meant to contain what was on the other side, similar to prisons and penitentiaries.
Step 8 - Hunt Monsters
An ominous noise is heard from the other side of the door. Since Rookie has to stay behind, you are asked to investigate. Click Closed Gate to go through. Hunt: 10 Dolor, 10 Venenum, 10 Twin Caputs. Optional: Go to the yellow mark on the map to unlock the Learning about Morning daily quest.

Long dialogue explains that Rekenber's annex lab, Regenschirm, was occupied by assailants that looked like Heart Hunters under the command of someone named Chelin, a former captain of Rekenber's security team.
