How the quest starts
You do not pick this quest up from a character. Beat any Oathbound fencer and the quest appears, whatever chapter you are in. PowerPyx places the first items near the Battlefield’s Onslaught Arch Lantern and the first quest step at the Valley of Ashes Demolished Path.
Several guards sit behind abilities you get later, so you will not clear the list in a single pass. Return with the pistol, Grapple, Stasis or Shield power when a route is blocked.
How to beat the duellists
The Eternal Guards share a fencing style that the game reuses later: PowerPyx notes that Justicar Aurelius fights like an Eternal Guardsman in his first phase, and Nephtis Superioris leads the order. Treat each duel as practice for those main bosses. Learn which thrusts can be parried and dodge red unblockable attacks rather than trading hits.
Opening the sealed Fortress room
With all seven pyramids combined into the Mysterious Stone Slab, fast travel to the Fortress Courtyard Lantern and walk back down the corridor where you fought Bastien. Use the slab on the triangular stone mark at the end of the corridor. Read the Codex of the Oathbound on the round table to complete the quest.
Four chests in the room hold an Empty Ferrofluid Flask, three Sands of Time, three Remnant’s Return and a Quintessential Blade Material. Bastien’s emblem has to be taken from his body after the duel.
Do it before the High Tower
Guides advise finishing the Oathbound before you climb the Fortress High Tower, because fast travel is unavailable after that point. Completing the quest also unlocks the We Wear the Same Colours achievement, one of the rarer ones in MetaBot’s data.
