Tolvann

Planetary Data
A close moon referred to as "Dukkan" keeps grip on the monolithic sandstorm that engulfs the planet, making it arise way past the atmosphere akin to other satellites on their planet's ocean, thus creating a dust cycle the inhabitants were evolved to whitstand, both as animals and as a civilization, buildings above the ground are mere markers that serve the sole purpose of welcoming wanderers into trenches and caves, such is the life of the average Tolvannian, they developed an underground society. Resurfacing became only necessary for sunlight and the fruits partially buried beneath the dust, gifted by stoic trees, soul survivors of the periodic whiplash Dukkan causes.

The surface itself is unsuprisingly barren, a thick layer of dust rests on the ground whenever it isn't flying with the wind and the gravitational pull, below the surface a cavern complex serves as shelter from the sandstorm, they became so commonly transitioned Tolvannians decided to create cities long ago, cavernous animals and water chasms are sufficient for survival.

Inhabitants
Tolvannians have evolved to have long ears that cover them from the dust. They have tiny horns sticking from the top of their heads with no apparent purpose other than making Tolvannians seem tougher.

The dust cycle and the day-night cycle aren't the same on Tolvann, because of this, Tolvannians have evolved to have night vision, allowing them to lurk at night and underground.
