Background

You have reason to believe that a famous Legion commander, Etienne du Marney, might still be alive in the Aranoi Desert. He could prove a valuable ally… if you can find him.

Walkthrough

Travel to the Aranoi Desert

You’ll need to travel through the Causeway Hub to reach the Aranoi Desert. If you started the DLC via an “endgame autosave” then you’ll begin in the hub. Otherwise, you’ll have to travel through the Causeway in the Grand Chapterhouse in Stonebridge City to get there. Once in the hub, you’ll find the Causeway to the Aranoi Desert on the western side.

Travel to the Abbey of St. Hiram

As you explore the desert, you’ll come under attack by skeletons, including a Skeletal Giant (#2). You’ll complete this objective when you reach the entrance to the abbey, located in the northern part of the desert (#7).

Talk to Sister Eleanor

When you enter the abbey courtyard, you’ll learn that Sister Eleanor would like to speak with you. You’ll find her inside the main abbey building (#11). When you talk to her there, she’ll inform you that du Marnay went into the vault beneath the abbey years ago, and never came back out, and that only Simeon, the abbey’s former abbot, knows how to open it up so you can go inside and find out what happened. Completing this conversation will also complete the quest, and earn you 1535 xp.
