The Titan Rockbore is an anchored Titan originating from the World Tree. Its bores extend well beyond scanner range, and it seems to reach every biome in the explored regions. Angel Combs feed off the Titan Rockbore, parasitizing it to create the Proteavirus.
Appearance
The Titan Rockbore adopts a shell-like appearance. Its topside is a light blue with its bottom segment transitioning into a pale white. The surface texture is bumpy with the shell having multiple bumps and imperfections.
Databank Entry
Source: Scan the Titan Rockbore
This enormous colony organism (Lithodont titanicae) resembles a spinal cord protected by a thick crablike shell. It extends beyond scanner range in both directions, growing through fractures in the seabed rock.
-
Hollow interior: The interior of the bore contains at least two large flooded channels—one strikingly radioactive. The ancestral form may be a pyrosome (a sea squirt).
-
Poor health: Most of the zooids in the bore are dead, leaving only a mineral skeleton and a hydrocarbon-polymer shell. The interior channels have clogged.
-
Unknown metabolism: The bore has no apparent food supply. It may have derived chemical energy from minerals, but if so, its bacterial symbiotes have fled. It is starving.
-
Viral activity: The surviving tissue is infected with large RNA virus similar to Earthly giant sea viruses. The bore's anatomy includes receptor sites that encourage viral infection and reproduction. Further analysis required.
Assessment: Entirely unknown organism - investigate further, determine origin and ecological niche.

Trivia
- The species name "titanicae" is shared with a real species of bacteria named "halomonas titanicae", which was discovered at the sunken wreck of the Titanic.
