Zairis
Zairis (Old Draconic for Iris' stone) is a terrestrial life-harboring planet of unknown (or undisclosed by the Primordials) age. Roughly two thirds of its surface are covered in water, and it is the second closest to the sun of the Zairian System's four planets.
History
Formation
Zairis was created by the seven Primordials, most of which continued to shape and develop it for a long time after its initial formation by the Primordial Rrequtaas' sacrifice of his body. Randegosa then created the sea, and Ardothun breathed out an atmosphere to engulf the young planet. Once this work was done, Iris seeded Zairis with life, and Endacil pledged to take care of the afterlife, while Morik and Abraxas worked on their own designs for the world away from the others.
Geography
Zairis has three distinct current landmasses as well as one former landmass that was blasted into what is now the Thousand Eyries in the Pre-Draconic Era.
Dunieth
Dunieth is the largest of Zairis' continents in area as well as the one with the largest climate variance. It is notably the location of three of the Six Great Powers - the Nikosian Empire, Ka'aras Sovereignty, and Nethron - as well as the Underdeep Blightlands.
Frysgard
Frysgard is a continent that covers the north pole of Zairis. It's mostly covered by the megaglacier called Glasjer, but it has habitable regions like Sydstrand Coast and the Nordheim Mountains poking out from under it.
Mithros
Mithros has been the middle point of various great upheavals that Zairis has seen over its many eras, most notably the appearance of both dragons and humans in the world.
