Hidden deep beneath Fisch’s crumbling halls, the Ancient Archives Door guards its secrets behind an intricate fragment puzzle. Solving it demands more than luck-each piece must be placed with precision to awaken the forgotten mechanism that has slept for centuries.
All Items Required to Unlock the Door to Ancient Archives
To open the Ancient Archives Door in Fisch, players must gather several rare items scattered across different areas. These include the Ancient Fragment Pieces, which come in four colors-red, blue, green, and yellow-each hidden in puzzle rooms guarded by traps or elemental challenges. Once all fragments are combined at the central altar, they form the Complete Archive Key. Players may also need a Charged Crystal Core to power the mechanism near the sealed door. Bringing all these components together triggers the door’s ancient mechanism and grants access to the hidden chamber beyond.
There are several new items introduced in this update called Fragments. In Fisch, the Ancient Isles holds four types of Fragments, and you will require all of them to unlock the door to the Ancient Archives. These are:
- Deep Sea Fragment
- Solar Fragment
- Earth Fragment
- Ancient Fragment
To reach the Ancient Isles, spawn a boat from the Shipwright on your island and head to these coordinates:- XYZ: 5833, 125, 401 after getting a Fisch GPS. As you cross the Nearby Ancient Isles region, a new soundtrack will start playing, indicating that some obstacles will rise on the ocean surface.
There might be bombs and spikes randomly coming your way. So keep steering carefully and try not to take any damage if you don’t have a powerful boat. Upon reaching the Ancient Isles, you may look for the Fragments before opening the door.
How to Get the Deep Sea Fragment
The Deep Sea Fragment can be found by completing the Coral Depths expedition located beneath the western reefs. After reaching the area, activate three glowing pylons in sequence to lower the pressure barrier. Defeat the Abyssal Sentinel guarding the fragment chamber, then collect the fragment from the central pedestal. Make sure to have at least one oxygen module equipped before entering, as the zone drains your air supply faster than usual.
The Deep Sea Fragment, as the name suggests, is located under the sea. Head to the western part of the Ancient Isles, where you will find a waterfall. If you turn on your Fish Radar, you will notice that Xiphactinus is found in this region. Dive into this shaded region and swim to these coordinates:- XYZ: 5843, 75, 383. You will find the blue-colored Deep Sea Fragment submerged in a corner.
How to Get the Solar Fragment
The Solar Fragment can be obtained by solving the prism light puzzle found in the western chamber of the Ruined Observatory. Activate the crystal pedestals in the correct sequence so that the beams align and strike the central mirror. Once the light hits the core structure, a chest appears containing the Solar Fragment. Make sure to defeat nearby sentinels before interacting with the chest, as they will attack once the mechanism is triggered.
The Solar Fragment is located at the top of the tallest hill in the Ancient Isles, specifically at– XYZ: (6074, 443, 681) coordinates. To reach the peak, you may consider using the zip line present at the coordinates (6160, 273, 357), located behind the wooden tower on top of the Merchant.
Once you reach the peak, you can pick up the Solar Fragment; however, this can be done only during a Solar Eclipse. If no such event is happening in your server, you can manually start one by using the Eclipse Totem found inside the cave, where you will get the Earth Fragment.
How to Get the Earth Fragment
The Earth Fragment is hidden within the lower cavern near the Fallen Pillar site. To access it, activate the nearby elemental totems in the correct order, matching the symbols found on the surrounding walls. After the sequence is complete, a small chamber opens where the fragment rests on a pedestal. Collect it and inspect the markings on its surface-these will later align with the mechanism that controls the Ancient Archives Door.
Having collected the Solar Fragment, head straight in the southwest direction till you reach the cliff, where you notice a big pink flower and some fences below. Jump down and land before the fences to find a secret cave hidden by some leafy structures. Head inside the cave, and you will find the Earth Fragment, the Eclipse Totem, and the Phoenix rod.
Pick up the Earth Totem. If you wish to manually start the Solar Eclipse, you may buy an Eclipse Totem for 250,000 cash. I recommend server hopping to get into an ongoing solar eclipse event instead of buying this totem to save money if you are a mid-game player or just a beginner.
How to Get the Ancient Fragment
The Ancient Fragment is hidden in the lower chambers beneath the western hall of the Archives. To obtain it, activate the three rune pedestals lining the corridor by aligning their symbols with the ones etched on the nearby murals. Once all pedestals glow, a secret compartment will open at the base of the central statue, revealing the fragment. Collect it carefully-the chamber’s traps reactivate after a short delay, so move out quickly once you have it.
The Ancient Fragment can be found only through fishing in the Ancient Isles region. This might take a little while as the item is quite rare and might be the most difficult one to collect.
You should consider returning to the area where you got the Deep Sea Fragment and fish, specifically in the Xiphactinus area, to have the best chance of finding this item. Use a rod with high lure speed, like the No-Life rod or Rod of the Depths, and the Rapid Catcher/Instant Catcher baits to fish faster in the game.
How to Unlock the Ancient Archives Door in Fisch
The Ancient Archives Door in Fisch can be opened by completing the fragment puzzle hidden across the chamber. Players must collect all fragments scattered around the area and arrange them correctly on the door’s panel. Each fragment aligns with a specific symbol that glows once placed in the right spot. After assembling all pieces, a short sequence triggers, and the door will open, granting access to the deeper sections of the Archives.
Having collected all four Ancient Fragments, you may now head to the cave that leads to the Ancient Archives Door. You will require an additional three players to complete a task in the cave of the Ancient Archives. So bring three of your friends and perform the following steps to reach this area and open the Archives door:
- Head to the Western part of this island, where you will find a crashed Meteorite.
- Use the Zipline near the Meteorite to go near the waterfall, where there is an abundance of Xiphactinus. Here, you will require a Glider (found in the Ancient Isles at 6075, 195, 260) to reach the area behind the waterfall.
- Now, come to the topmost cliff near the wooden tower and jump in the direction facing the waterfall. Make sure to use your Glider the moment you make the jump.
- Skillfully make your way inside the cave behind the waterfall. Head inside, and you will find a pit and a rope attached to a side.
- Use the rope to go down the pit. Any other method, such as jumping into the pit, will cause instant death.
- At the bottom lies the gates to the Ancient Archives, with a big keyhole image at the center and certain symbols around them.
- You may bring all fragments and input them into the pillars or ask your friends to place the fragments. It doesn’t matter who is placing the fragments.
- The Deep Sea Fragment will go into the Blue Pillar. The Solar Fragment will go in the Orange Pillar. The Earth Fragment will go into the Green Pillar. Lastly, the Ancient Fragment will go into the Purple Pillar.
- Each of you must choose one pillar and stand on the pressure plate in front of it. Now, rotate the pillar so that you face the fragments.
- This will unlock the door to the Ancient Archives only for you four players and remain closed for others inside the server.
What Is Inside the Ancient Archives in Fisch
Hidden behind the sealed doors of the Ancient Archives lies a vast chamber filled with glowing relics, ancient tablets, and mechanical constructs from a forgotten civilization. Shelves line the walls, each containing encrypted scrolls and fragments tied to the game’s deeper lore. Strange energy pulses from the central console, hinting at a powerful mechanism connected to the fragment puzzle that players must solve to access the Archives’ secrets.
Now that the door is open, you have finally unlocked the Ancient Archives in Fisch. Once you head inside, you will find a bridge broken in a few places. Use the Glider to cross these areas and get to the next point. At the end of the bridge, you will find a stone Anvil with a green glowing base.
Here, you can craft ten new rods by collecting all the required items. Some might require fishing at certain locations to get the rods, while some have a high-level requirement to unlock the rods. Most of these are endgame rods, and it is recommended to complete at least 70% of your Bestiary, The Depths region, and level up till you can unlock them.
Where to find all four Ancient Fragments with coordinates
Deep Sea Fragment (Blue)
Dive underwater at the base of the waterfall on the west side of Ancient Isles, approximately at coordinates XYZ: 5843, 75, 383. Currents can be strong, so Basic Diving Gear helps push through to grab it from the underwater spot.
Solar Fragment (Orange)
Located at the mountaintop peak above the island Merchant on Ancient Isles. Take the zipline right of the main waterfall approach to the camp, climb to the Leedsichthys pod area, then jump up cliffs to the lone tree spot near the highest point.
Earth Fragment (Green)
From the Solar Fragment position (fragment on your left, large tree on right), head southwest down cliffs. Look for a fence protruding at approximately XYZ: 5943, 269, 896; drop in to find a cave behind ivy with a small shop-pick up the free fragment inside.
Ancient Fragment (Purple)
Fish it as a random drop in Ancient Isles waters, best at Xiphactinus abundance zones around coordinates XYZ: 5836, 125, 401 (near main island spots). Use high-lure rods like No-Life or Depths Rod with Rapid/Instant baits; listen for a tapping sound and pop notification when hooked.
How to open Ancient Archives door with fragments
To open the Ancient Archives door in Fisch, collect the four fragments (Deep Sea/blue, Solar/orange, Earth/green, Ancient/purple) and bring three other players to the cave behind the west waterfall in Ancient Isles (coords ~XYZ: 5833, 125, 401). Use the rope to descend safely into the chamber with the four colored pillars and pressure plates.
Fragment Placement
Insert each fragment into its matching pillar: Deep Sea into blue, Solar into orange, Earth into green, and Ancient into purple. Fragments can be distributed among the four players.
Activating the Puzzle
This must occur during an Eclipse event (every seven in-game nights). Each player stands on the pressure plate before their pillar and rotates it so the emblem faces them-the door glows when aligned correctly and unlocks temporarily for your group.
Crossing Inside
Glide across the broken bridge using a Glider to reach the stone Anvil for crafting new rods. The door stays accessible for your session even if you rejoin.
