The Oathbound Side quest · City of Orphans

A step-by-step walkthrough built from the quest's journal entries, clue letters and reward data.

1. Defeat an Eternal Guard and find the hidden emblem under his shirt — that starts the quest.
2. Collect all seven Oathbound emblems from Eternal Guards: Valen Duroc, Lucien Lafontaine, Étienne Vauclair, Jean Pierre Polnaire, Severin Susse, Adrien Casell and Bastien Beaufort.
3. Read A Letter from Bastien Beaufort (about 89 m from Tribunal Square, City of Orphans): he summons his brothers to 'the Chamber' in the castle.
4. The quest also tracks seven Mysterious Stone Pyramids from fallen Eternal Guards; assembled into the Mysterious Stone Slab they look like a key 'connected to the ruins of the old castle'.
5. In the castle's hidden chamber — the Fortress, where the Codex of the Oathbound lies about 93 m from the Courtyard Lantern — the truth comes out and a final duel ends the quest (step 9).
6. Reward: no item, but it unlocks We Wear the Same Colours, held by about 0.2% of Steam players.
