The Stellar Blade Lost Ark side quest becomes available after traveling to the Great Desert for the first time. The quest is given to you by Mann in Xion. He is in the middle of the Presence Chamber.
Beginning the Stellar Blade: Lost Ark Side Quest
Speak to Mann in the Presence Chamber and select the dialogue option “Radical.” Mann tells you about a difficult group he’s been dealing with that is spreading misinformation. One has gone missing and they need to track him down. Mann asks if Eve is willing to lend a hand.
This starts the quest and your new objective is to search for the rebel in Xion’s Alley, which is marked in the top right corner of Xion’s map. There is a body behind the shops. Interact with it and collect the document called “Introducing the Ark-Tech’s Ark!”
Eve decides to investigate the place called the Ark, which is just down the alley and up a set of stairs. There is a panel next to the door that requires a code. Next to the code box is another document called “Experience Ark-Tech’s Ark!” It talks about a puzzle system installed outside the Ark with the hint: “Turn Xion, turn clockwise”
Finding the Ark Puzzles
There are six ark puzzles around Xion. The first one is easy to find. It is next to the Ark entrance at the bottom of the stairs, a little to the right. A 0 appears on the screen when you interact with it.
The next puzzle is next to the tables in a cafe. Another symbol appears there too.
The third puzzle is on a small building and a U symbol appears when you interact with it.
The fourth puzzle is near Sister’s Junk on a set of stairs and a backwards 3 appears when you interact with it.
The fifth puzzle is by a set of stairs in the middle of Xion and it has a K.
The last one is in one of the branching sections of West Xion, by a shop with Japanese writing and a caution sign.
Investigate the Ark
All of the letters form the passcode for the Ark. Head back to the entrance and you can now guess the code. The code for the Ark is θμκαεγ.
Go inside the Ark, where you’ll find another body next to the entrance. Collect the memory stick called “Lament of the Trapped”. Take the elevator at the end of the hall down to the lower floor. Scan the area to highlight the clues inside.
There are three bodies to interact with, each with a memory stick. There is one body behind the wall with the “Who Are You Guys?” memory stick. The second body is by the rubble with the “Let Me Out” memory stick. The third one is by a chair with a memory stick called “Monologue of a Trapped Man”.
Once you interact with the screen inside one of the rooms, everything goes red and the doors lock themselves. Your new objective is to find a way out. Destroy the two panels with flashing red lights on either side of the nearby door and it will open. There’s another panel on the right. Destroy that and take the elevator back to the top. Destroy the panel next to the exit and you’re free.
Rewards for Stellar Blade: Lost Ark Side Quest
Return to Mann and select the “Radical” dialogue option. Eve tells him the news about the radical’s death and the deaths of the others. You’re rewarded for completing the Stellar Blade Lost Ark side quest with 2x Smart Mine, 2x Shock Grenade, and 2x Pulse Grenade.
