The Frosthearth

A planet orbiting a K-type orange dwarf star, significantly cooler than Earth. Its atmosphere is rich in nitrogen and carbon dioxide, with a lower oxygen content, leading to a denser, greenhouse-warmed atmosphere despite the cooler star. Liquid water exists primarily in subsurface oceans kept liquid by geothermal activity, with only small, ephemeral surface lakes and rivers in equatorial regions. Dominant habitat is subterranean, within vast cave systems and ocean trenches.

Abyssal Vent Stalker

Shaped by 🌾 abundance

A larger, more robust predator that has capitalized on the increased resource availability, becoming more generalized in its hunting to take advantage of a wider array of prey.

Why it evolved

With food becoming unusually plentiful, selection favors individuals capable of exploiting this surplus, leading to an increase in size and a broader appetite. This Abyssal Vent Stalker has grown larger and its metabolism has increased to support this, allowing it to consume a wider variety of prey found in the deep cave systems. However, this specialization towards exploiting the abundant resources comes at the cost of reduced reliance on its highly specialized chemoreception and low-light vision, making it potentially vulnerable if the resource boom ends or prey distribution shifts.
