+# Alien Arches+ ++ +**Alien Arches** are large constructs of the Precursor Race. They resemble large gateways with a bright green, semi-transparent portal within. The Prawn Suit and the Seamoth have the ability to enter Alien Arches.+ +When the player enters an Alien Arch, it plays an SFX similar to when a Warper warps the player. Some of these are located within Alien Arch Caches, which are caverns containing the Alien Arches found in certain biomes. Only one of these caches contains a Principal Arch, while the other five contain Auxiliary Arches. The player is able to walk on the seafloor when inside these caches.+ +## Arch Types+ +### Principal+The Principal Arches have pedestals and must be powered using an Ion Cube. They warp the player to an Auxiliary Alien Arch.+ +### Auxiliary+The Auxiliary Alien Arches do not have pedestals, and their corresponding Principal Alien Arches must be activated before these gates can be used.+ +## Locations+ +### Principal Arches+ +| Location | Connects To | Coordinates |+| :--- | :--- | :--- |+| Mountain Island | Floating Island | 340 61 903 |+| Alien Thermal Plant | Quarantine Enforcement Platform | -35 -1210 112 |+| Primary Containment Facility (PCF) | Bulb Zone | 327 -1429 -279 |+| Primary Containment Facility (PCF) | Crag Field | 169 -1431 -367 |+| Primary Containment Facility (PCF) | Mushroom Forest | 357 -1430 -313 |+| Primary Containment Facility (PCF) | Ghost Forest | 189 -1428 -405 |+| Aquarium | Primary Containment Facility | Moonpool: 421 -1509 -628 |+| Aquarium | Mountains | 273 -1568 -360 |+ +### Auxiliary Arches+ +| Location | Connects To | Coordinates |+| :--- | :--- | :--- |+| Floating Island | Mountain Island | -662 2 -1050 |+| Bulb Zone | Primary Containment Facility | 1356 -301 693 |+| Crag Field | Primary Containment Facility | -52 -296 -1401 |+| Ghost Forest | Primary Containment Facility | -886 -612 1040 |+| Mushroom Forest | Primary Containment Facility | -803 -227 409 |+| Quarantine Enforcement Platform | Alien Thermal Plant | 384 -92 1137 |+| Mountains | Primary Containment Facility | 463 -165 1353 |+| Primary Containment Facility (Moonpool) | Aquarium | 336 -1434 -478 |+ +## Data Bank Entry+ +This structure's intended purpose is unclear.+ +**Theories on Function:**+* Ceremonial or religious role+* Industrial applications+* Advanced transportation network+ +**Assessment:** Further research required.+ +Scans indicate this arch was left inactive when the facility was abandoned.
