The most conspicuous feature on the surface of Maltorian I is the massive volcanic fissure that dominates the planet's central latitudes. Known locally as the Scarlet Sea, this string of geothermal vents loads the upper atmosphere with a layer of fine volcanic silt which obstructs the sunlight and contributes to freezing temperatures at the ground level.
The largest continents, in the northern and southern hemispheres, are buried deep beneath thick glacial flows. However, in the equatorial region, an archipelago rises above the Scarlet Sea where the terrain is more habitable. Anargoloth Island is the center of planetary traffic and has evolved over the centuries into a sprawling megalopolis that began in Colony Prime and includes the merchant district of Jahari. Just west of Anargoloth lies Mount Wuji, a moderately active volcano that rises 12,962 feet above sea level.
The colonial population of Maltorian I are an adventurous lot. Hunting and ice-fishing are popular activities and the planet hosts a community of vent-racing enthusiasts who compete annually at the time of the blossoming of the local Stoneflowers.
