ArcheAge Chronicles Missing Officer: Find Edward and Prison Key Location

Missing Officer sends you past the dimensional rift into Diamond Shores, a foggy pirate settlement built from wooden scaffolding and half-sunken ruins. The quest ends when you find Edward behind bars. The follow-up, Rescue Plan, asks you to find the key that opens his cell, and that key sits in the water right outside it.

Quick answer: Edward is in a wooden cage on the far side of Diamond Shores’ flooded cavern. Talk to him, then dive into the pool in front of the cell to grab the Prison Key.

Where to find Edward in Diamond Shores

Once you cross the rift, the game warns that fast travel doesn’t work beyond the boundary. You have to cover Diamond Shores on foot and in the water. The quest tracker reads “Find Edward (0/1).” Follow the blue objective marker on your compass as it pulls you through the settlement toward the cavern at the back of the area.

The docks and shacks are full of Pirates of Madness. You’ll meet Archers, Warriors, Illusionists, and Juggernauts, plus a regular Pirate or two. Several fights take place on narrow walkways over the water, so you can drop into the sea and climb back up wherever the boards run out.

There’s a Brewing Furnace near the entrance where you can craft Lifeflow Potions before you take on the pirate camps.

After Garret and the Awakening Nui Statue, cross the wooden deck. Climb one of the ladders to reach the cliffside catwalks, then follow the elevated walkways until you can drop to the ground near the cavern.

The last stretch is a swim. Cross the flooded cavern basin toward the torchlit wooden structure on the far side, where Edward and another prisoner, Kevin, are locked in.

Prison Key location and how to unlock Edward’s cell

Talking to Edward through the bars completes Missing Officer and immediately starts Rescue Plan. The new objective explains that the key is missing and tells you to use Kevin’s hint to search the area. You don’t have to search far.

Interact with the locked wooden gate to speak with Edward. Your tracker should switch to Rescue Plan with the objective “Find the prison key (0/1).”

Face the pool just ahead of the cell and dive beneath the surface. The key is underwater; you won’t find it on the ground around the cage.

Swim down to the bottom and look for the glowing yellow plants on the seabed. The Prison Key rests among them, and an interaction prompt appears once you get close. Interact to pick it up.

Resurface and swim back to the cage. The objective changes to “Find the prison key and unlock the door (0/1).”

Use the key on the cell gate to release its lock. The gate swings open, triggering a brief cutscene featuring Edward and Kevin.

Unlocking Cell — Unlocking the gate frees the prisoners and starts the rescue cutscene. Shown at 05:48 in RIFAS’s video. Image: XLGAMES

You’ll know it worked when the gate swings open and the cutscene starts. Rescue Plan’s objective then clears from the tracker. On a character at this point in the story, the reward XP can also trigger a level-up to Lv. 8.
