Annwyl
Homeworld of the Voidi
Annwyl is not a world that was meant to last.
It is the shattered remains of an ancient exoplanet, struck by a wandering moon centuries ago. What survived the collision fused together—planetary crust, lunar mass, and debris locked into a single, unstable body. The species stranded upon that broken moon endured. Over time, they became the Voidi.
Annwyl is a world of constant survival.
Environment & Climate
Annwyl is a hyper-frozen planet, with surface temperatures ranging from −100°C to −300°C, depending on which face of the planet is turned toward its dying star. That star, old and failing, provides barely enough light to see on even the clearest of days.
For most of the year, Annwyl exists in near-permanent darkness.
Orbital Mechanics
-
Orbital Period:
Annwyl completes a full revolution around its star every 248 Earth years. -
Rotational Period:
A single day on Annwyl lasts approximately 6.4 Earth days, producing long, brutal cycles of exposure and cold.
Geological Instability
Formed from the violent collision of planetary and lunar remains, Annwyl is geologically unstable.
-
Tectonic activity is constant, with plates grinding and shifting beneath the frozen crust.
-
Vast gorges can form in a matter of decades.
-
Entire mountain ranges rise rapidly, reshaping the surface without warning.
The planet is never truly still.
Life & Longevity
Voidi are not adapted to Annwyl by design—but by endurance.
While they are capable of reaching ages of up to 690 years, most do not die from age. Instead, they succumb to the elements as their bodies slowly lose the ability to generate and retain enough heat to sustain life.
On Annwyl, survival is temporary.
Longevity is earned.
Nothing lasts forever.
