Description
Tarutaja is actually a large gas giant moon, not a standalone planet, but it has a molten core like a terrestrial planet and had to be terraformed to support life. Before it was habitable, it was like Mars but extremely hot, averaging 236 degrees F on a good day. Terraformed Tarutaja averages 115 F on a typical day. Also there's a green strip close to the ice caps, because the ice is water and also provides coolness, so life tends to thrive in the "green belts" around the poles.
Hrr'gthr-Sypos is known for its colorful continents. The reddish brown continent is chock full of wyverns, while the blue continent is full of dragons.
Seltenia's geographical layout separates the world into two major biomes: a tropical strip which rides the equator, and two icy poles with solid land below the snow. The Arkesiel who inhabit the icy regions have white plumage, while tropical Arkesiel are brightly colored.
While all of these are terrestrial planets with molten cores and volcanic activity, Seltenia has never been through continental drift because the planet's crust is not fragmented into plates. Tarutaja has faultlines and tectonic activity, but it has so little water that it's one big supercontinent anyway. The supercontinents of Seltenia are called Aisie and Flearenie. Aisie is the cold one and Flearenie is the tropical belt that wraps around the equator.
