Sealed OS¶

Guide¶

Sealed OS is the Episode 17.1 story memorial for the quest Old Memories. You sneak into the sealed OS mine near Einbroch, only to find Ridsh, Dien and Cotnes already inside. You team up with them to break through the facility's devices and follow the railway to its end.

Requirements and entry¶


Quest	Old Memories (Episode 17.1 main story), after scouting the mine for the Rebellion Crew
NPC	Rebellion Crew at `/navi ein_fild03 278/269`
Party	Required. Only the party leader can open the gate.
Time limit	2 hours

The leader talks to the Rebellion Crew and picks Open the gate., then everyone talks to him and picks Go inside.

Walkthrough¶

The party leader talks to Ridsh at the landing point (188/45). Dien and Cotnes show up, and the exits behind you are blown shut.
Mutants jump the group. Dien and Cotnes hold one side while you kill a Dolor #20361 and a Twin Caput #20365.
When both are dead, a Suspicious Device appears at 212/41. Click it and pick Crush it. Ridsh tells you to follow the railroad tracks.
Further along the tracks (around 112/108), Dangerous-Looking Devices at 115/112, 115/126 and 115/144 push you back whenever you walk into them. Break the three Thick Wires at 137/107, 137/123 and 137/139. Each wire shuts down one device.
When all three wires are cut, keep following the tracks to the locked gate near 114/217. Talk to Dien or Cotnes there. They suggest going around the door to the right.
Talk to Ridsh at 146/221. Est turns up, and after some arguing the road opens.
Follow the railway north to the end (259/360). Seven trap spots along the way each spawn two Heart Hunter mutants (Heart Hunter Bellare #20355, Heart Hunter Sanare #20357, Dolor #20361, Venenum #20363 or Twin Caput #20365) the first time someone walks over them.
Talk to Dien at 259/360 to finish the story. She sends you back to /navi ein_fild03 258/267.

You get these from Dien while your Old Memories quest is active:
