Before you start

Story progress
Chapter 5 or later
Fandom's availability table: Chapter 5 Started. Xeno Series Wiki files it under Chapter 4 (after Mòrag joins in the Old Factory), so it is likely doable from late Chapter 4.
How the quest unlocks
Unlock Perceval's Key Affinity (Affinity Chart) level 3, then with Perceval in the party the quest triggers from Ellenora, who is being threatened by thugs in a back alley of Nharil Central Plaza in Alba Cavanich. Listed under 'Chapter 5 Started' on the wiki availability list with no extra requirement; Xeno Series Wiki lists Nia, Tora, Morag and Pyra in the party (Zeke not required).
Also required
  • Perceval's Key Affinity level 3 unlocked
  • Nia, Tora, Morag, Pyra and Perceval in the party (per Xeno Series Wiki) — Pyra is absent during Chapters 8–9, so the window is Chapters 4/5–7 or from Chapter 10
  • Merc Group required: five Merc Missions in total ('Brought to Justice 1-4' and 'Unjust Organization')
  • Two steps only progress late at night (00:00-5:00)

Walkthrough

  1. With Key Affinity 3 unlocked, find Ellenora being harassed in the backstreets of Nharil Central Plaza and speak to her after Perceval scares off the thugs.
  2. Gather information about the nefarious goings-on around Alba Cavanich by talking to citizens.
  3. Head to Ellenora's house, deep in the backstreets of Nharil Central Plaza.
  4. Go to the meeting in the Old City of Teddim late at night - it only occurs between 00:00 and 5:00; the key to the Junction Control Room is found in Delize's Infirmary (Neoseeker notes the infirmary is guarded by the Unique Monster Judicial Kollin).
  5. Complete the Merc Mission 'Brought to Justice 1'.
  6. Complete the Merc Missions 'Brought to Justice 2', 3 and 4 in sequence.
  7. Head to Jakolo's Inn, then return to Ellenora's house - the party finds her murdered; check the corpse in the backstreets.
  8. Gather info about the Bloody Lobsters through the Merc Mission 'Unjust Organization'.
  9. Talk to Pupunin in the Chairman's Room at the Argentum Trade Guild.
  10. Investigate Pupunin's den on Argentum's Salvage Deck late at night - again only between 00:00 and 5:00.
  11. Defeat the Bloody Lobsters on the Salvage Deck: Gale Rocke, Clean Driver and Silt Driver - then immediately fight a second wave of Gale Rocke, Clean Driver, Silt Driver AND Lethal Bradly together.

Good to know

  • This quest is infamously merc-heavy: five separate Merc Missions ('Brought to Justice 1-4' plus 'Unjust Organization') must be completed, so keep a capable bench of spare Blades and expect real waiting time.
  • Two steps are strictly time-gated to 00:00-5:00 (the Old City of Teddim meeting and Pupunin's den) - rest at an inn or skip time if nothing is happening.
  • The finale is two consecutive fights - the second wave repeats all three enemies and adds Lethal Bradly - so do not exhaust your party gauge on the first wave.
