Spoiler (BZ) Read at own risk

This article contains unmarked spoilers. Players new to the game would want to avoid or be cautious toward this article.

The Laboratory Cache is found in the Ghost Canyon of the Lost River. It was set up to study the Ancient Skeleton and several other specimens within the Lost River. This Cache is unique in that it requires the Orange Tablet found in the Deep Grand Reef Degasi Base to unlock. Inside the Alien Cache, three containers with bone samples and three containers with local Fauna samples can be found, there are various pieces of Precursor lab equipment scattered around as well as three Ion Cubes at the far end. A Cuddlefish Egg can be found on the workbench at the far right of the cave. Crabsquids may be encountered outside of the entrance cave. Take caution when approaching the cache and keep any vehicles near the ceiling.

Data Bank Entries[]


The skeleton of a million-year-old, armored carnivore. Projections suggest this lifeform would have been larger than any living creature encountered on the planet.

The oceans of the time would have been very different to support lifeforms of this size, with more open geography and many more individuals in the leviathan range.

These fossils likely came from an ancient ancestor of the leviathans which inhabit the planet today. The relative size and delicacy of the bones suggests they formed part of the ear canal, or some other complex internal structure.

Local plants being held in stasis. The aliens evidently sought an extensive knowledge of the planet's ecosystem, which would have been necessary to support any live specimen research.

The large laboratory table and accompanying scanners incorporate technologies far beyond our current level of understanding.

- Equipment maintenance
- Staff maintenance
- Specimen analysis
- Specimen gene manipulation

The prominence and facing of these alien devices suggests they are some kind of probe or sensor. Their subject would seem to be the vast skeleton in the center of the cavern. The attached cable network may lead to a remote power station or data hub.

Assessment: Investigate

Extensive alien research data on the local fauna, with a special focus on their reproductive methods. Core conclusions have been synthesized:

- The aliens discovered the lifeforms on the planet have just one sex
- They observed local organisms engaging in asexual reproduction
- All healthy individuals tested were capable of egg-laying
- Eggs usually required genetic material from another of the species
- In rare case only one parent was required, with evolutionary mutation introduced by the effects of the environment itself

Research appears to have been focused around hatching conditions and genetic variations between parent and child.



  • The data bank entry for the bone specimens case states that they are bones from ancient relatives of living leviathans, possibly being ear bones. Despite this, all three of these bones actually belong to the Reaper Leviathan and can be seen in their skeletons.
