HyperBorea (Tsukuyomi-Amaterasu)

TIMELINE

This article takes place in the 24 & 26 centuries of Distant Worlds.

OVERVIEW

The planet HyperBorea, initially classified as DSO 76456-10857 Artifact or "The Forgotten Planet", is a temperate marine moon orbiting the Class IV gas giant Borealis. HyperBorea became a primary focus during the Distant Worlds expedition, especially following first contact with the Archangels and the activation of the Lotus Facility. Traces of HyperBorea were first detected during an early survey of the Lotus Facility on Nova (K2-18b). The crew, led by Mikail Deutron, included Harrison Wells, Vitas Vanir, and Victor Dastarian, alongside an undercover S.E.A. agent and a chemical expert.

HyperBorea defies conventional planetary science. Its relatively young age is an anomaly, sparking theories that it may have been crafted by the Archangels as a terminal to access their ancient technology. This theory was initially dismissed after a database access revealed the presence of an unusual metal on the planet—a dual-graviton string-bound structure caused by interactions with Fractons. This finding led some to speculate that HyperBorea might be linked to the Unknowns, ancient beings from a collapsing Fractal Universe known as the Bridge Architects. The Archangels are believed to have established a Library access point on HyperBorea for civilizations in the Shibui galactic region, near the "Eye of Horus" Nebula.

$S_{\text{dual-graviton}} = \int d^{11}x \left[ \frac{1}{2} \partial_{[\mu} h_{\nu]\lambda} \partial^{[\mu} \tilde{h}^{\nu]\lambda\rho\sigma} + \frac{1}{2} \tilde{h}^{\mu\nu\rho\sigma} \Box \tilde{h}_{\mu\nu\rho\sigma} \right]$ The new metal, far more exotic than the so-called Angelic Metal, was named Gravinium due to its unique dual-graviton bonding, which naturally causes gravitational anomalies. When manipulated, Gravinium's properties can be harnessed, making it the core material for constructing Bridge Rings, the gateways that enable passage through bridge space. This phenomenon has earned it the unofficial nickname "Dual-Graviton Interaction with Gravioli Sauce," humorously referencing the simulated diagram of its interaction, which resembles spaghetti weaving into a wobbling snake.

HyperBorea's oceans are composed primarily of tritiated water (T2O), containing unusually high concentrations of tritium (H3) the origin of which remains a mystery. Native sea life has evolved to thrive on tritium radioactivity, drawing energy from it to survive in the deep, high-pressure environments of the planet’s vast seas.

The planet’s atmosphere, composed of 72% CO2 and 28% O2, along with trace amounts of inert gases, is highly unsuitable for human habitation. Despite these harsh conditions, the local plant life has adapted to perform extreme photosynthesis, using the CO2 in the air to fuel its growth.

OCEAN LIFE

The oceanic life of HyperBorea remains largely unstudied due to the planet’s distance from the local stellar neighborhood and the complexities of exploring its deep waters.

TritoCarp

Near the surface, a common species known as the TritoCarp (scientific name: Tritiumo Carpio) thrives in the shallow seas. This fish primarily feeds on seaweed near the shores, where radiation levels are lower. During periods of solar eclipses caused by Borealis or at night, the TritoCarps migrate to deeper waters to feed on tritium hotspots. Physically, they differ from Terra’s Cyprinus carpio by having two antenna-like appendages above their eyes, which function as attenuators for detecting tritium hotspots through electromagnetic radiation.

Aplanulata HyperMeduzas

In the deeper depths of HyperBorea’s oceans, massive schools of jellyfish-like creatures known as Aplanulata HyperMeduzas float through the irradiated waters. These jellyfish are remarkably similar to Terra’s Aplanulata species, suggesting a curious case of parallel evolution. However, unlike their Earthly counterparts, the HyperMeduzas sustain themselves purely on tritium radiation and never rise from the depths of HyperBorea’s seas.
