Giant's Deep Core
A submerged sanctuary where gravity bends and time stands still.
The Giant's Deep Core is the vast, hollow interior of the water planet Giant's Deep. Unlike a solid world, this planet contains a massive subterranean ocean accessible only by riding the violent cyclones on the surface. It serves as a crucial location for uncovering ancient Nomai history.

- Cyclone on the surface
Lore & Background
The Nomai utilized this unique environment for advanced scientific research that required conditions found nowhere else in the system. The interior's distinct gravitational properties allowed them to study physics in ways impossible on solid ground, leading to profound discoveries about the nature of reality. Within the submerged ruins, travelers find records detailing how the ancient civilization designed the Sun Station, a device built in orbit around the star, intended to trigger a supernova to generate enough energy to power the Ash Twin Project's time loop. However, the Nomai never succeeded in triggering the supernova; the supernova the player experiences is caused by the natural end of the sun's life, not the Sun Station. The time loop is a consequence of the Ash Twin Project activating when the supernova occurs, not the cause of the supernova. This knowledge remains preserved in the dark waters.
In Their Own Story
The light of the surface fades as you descend through the sinkhole, swallowed by the deep blue silence. Bioluminescent flora flickers against the hull of your ship, guiding you toward floating islands of stone and ruin. Here, the water is still, holding secrets that have waited millennia to be heard.
Reader's Guide
The Nomai first discovered the planet's hollowness during their early expansion across the system. Recognizing the unique gravitational environment within the crust, they constructed research facilities on floating islands beneath the surface ocean. These structures allowed them to conduct experiments that would be impossible in normal gravity wells. Over time, researchers stationed here began observing anomalies related to temporal flow. They deduced that the recurring supernova was not a natural cycle but an artificial loop caused by distant cosmic entities known as the Hourglass Twins. This realization became central to their understanding of the universe's fate. Centuries later, players enter this submerged world through a massive sinkhole near the Eye of the Universe. Navigating the dark waters requires careful thermal management and oxygen planning. By exploring these ruins, travelers uncover the final pieces of the puzzle regarding the loop before facing the inevitable supernova.
Did You Know?
- Giant's Deep is a cloud-covered water planet containing several floating islands.
- The Nomai built a probe cannon in orbit around Giant's Deep to fire a probe in a random direction to locate the Eye of the Universe.
- The Nomai constructed a station in orbit around the star, the Sun Station, intended to artificially induce a supernova to generate enough power to send the probe's data back in time 22 minutes, but the Sun Station failed
- The Nomai discovered that, with enough power, they can send objects or information backwards in time using a linked pair of black and white holes.
- The Nomai were a three-eyed, fur-covered, antlered species that wore robes and large masks.
