Argiluu is a water world with 90% or more of its surface covered in an ocean of water, and an short-sleeve breathable atmosphere. The system has a population over one billion. This world is a satellite of a gas giant or another planet in the system. It is a member of Third Imperium in the Ushra Subsector of Dagudashaag Sector and in the Domain of Vland. Argiluu, as a member world of the Third Imperium, holds the estates of an Imperial knight and a baronet, and the fiefdom of a count. All three are members of the Imperial Nobility charged with overseeing the world. This world has a nearby Imperial Naval Base, capable of handling warships. During the Long Night this world was named Argiluu.

Astrography and planetology

The world of Argiluu is literally a "molten snowball": the crust, and much of the mantle of this formerly icy outer gas giant satellite, melted when its primary star evolved off the main sequence. Argiluu’s world-ocean is at least 60 kilometres deep, according to current estimates, its depths beyond the range of the most advanced densitometers. Terraforming has converted the original ammonia-water vapour atmosphere into a breathable nitrogen-oxygen mix.

The world has no land-masses as such - major settlements are tunneled into huge naturally-occurring rafts of foamed carbonaceous material known as "tarballs". Valuable organic chemicals are extracted from the tar, and the seawater is also rich in dissolved minerals.

History and background

Argiluu derives from the Old High Vilani for "no sound ocean" – the primitive sonar systems used in the earliest Vilani surveys produced no returns in many areas of the world-ocean.
