This article is about the Sea Emperor Leviathan Eggs. You may be looking for the Sea Emperor Leviathan or the Sea Emperor Babies.

Five Sea Emperor Leviathan Eggs are located in the Primary Containment Facility along with the last adult Sea Emperor Leviathan.

These eggs cannot hatch due to the Primary Containment Facility being built to match the ideal conditions for an adult Sea Emperor Leviathan, which seem to be significantly different than the ideal conditions for a baby, as a result, these eggs have been in this state for hundreds of years. The eggs are attached to a piece of Precursor equipment that supplies them with what is necessary to keep them alive.

The Player must hatch these eggs to cure himself of the Carar Bacterium in order for him to be able to leave the planet. To do so many plants must be gathered to create Hatching Enzymes.


The Sea Emperor Leviathan Eggs are very large, brown in colour, very similar to the skin of a Sea Emperor, they have many ridged layers, rows of bioluminescent cyan spots run vertically down opposite sides of the eggs.


After nine eggs had been laid by the Sea Emperor, the Sea Emperor Leviathan Eggs were taken away from their parent by the Precursors and placed on the Incubator Device. This is because of the unnatural hatching conditions of the aquarium, and the Precursors wanting to study the eggs, as their parent was incapable of producing enough Enzyme 42 due to their age, and their deduction that the unborn Sea Emperor Leviathans would be a more viable source.

Since the Precursors could not find a way to hatch the eggs, they took three[Citation needed] of the Sea Emperor Leviathan Eggs into the dissection room of the Primary Containment Facility, where they experimented on them. These three eggs were cut open, and a Sea Emperor fetus was removed from one of the eggs, terminated, and placed in a tank.

One of the nine eggs was taken to the egg lab, where it was also tested on, and left in a specimen tank afterwards.

Data Bank Entries

  1. (Shell)
    Uncommonly strong shell lining. Organic growth on the exteriors suggest these eggs may be hundreds, even thousands of years old.
  2. (Alien Tubes)
    Alien devices penetrate the outer shell layer. Likely designed to supply them with nutrients, and to isolate them from the surrounding environment.
  3. (Amniotic Sack)
    Unlike most other eggs where a nutrient supply is slowly exhausted by the embryo, these eggs exist in a form of natural stasis, likely awaiting ideal hatching conditions.
  4. (Fetal Organism)
    There is a high genetic match between these organisms and the leviathan in the vicinity. They appear to be stable and healthy.

It is likely that ideal hatching conditions vary considerably from ideal conditions for survival of the parent. The local ecosystem appears to have prioritized the latter.
