Spiraling through the outer reaches of the Rhinnal system, the planet Humbarine I has puzzled many planetologists since its original discovery. Yet even that date is a mystery that has somehow been lost amongst all the other records of the original exploration of the region.
Lacking a detectable atmosphere over much of the planet, the closest the mid-sized world comes to habitability is around the equator, with the weak rays of the sun warming the otherwise rocky surface just enough to crack, expand, and release some of the gases trapped beneath the surface. Given the coldness of the world however, these gases can not go far, and quickly condense back to the surface of Humbarine I in the form of a thick chemical ice which girdles the planet with with a band of off-white terrain. This leaves only the barest traces of gas to coat the planet in thin frost and gives it the odd sheen which can be picked up by telescopes on the other planets in the system.
