Uktarra

Uktarra, or the Northern Domain, was a supercontinent that existed between the Primozoan Period (around 895 million years ago) until the Cuiciloan Period (65 million years ago. It was the largest supercontinent to ever exist, peaking at around 70% of all land in Rathnir covered by the supercontinent curing the Certarian Period. It is a major part of geological history, existing consistently as a supercontinent the entirety of it's existence before the mass flooding after the Iridaceous mass extinction divided the landmass into Syltor, Helmia & Kasaĵa Andamʊk (modern Plagos & Najer). With the exception of the span of time between 450 - 220 million years ago with the Uktarran Schism, Uktarra dominated the north for the majority of the 600 million years long existence of the supercontinent.

The cultural impact of the continent is little compared to the other supercontinent, Yuldara, the longest lasting landmass after the breakup of Ÿbrāällpallkartulxemyyeqet during the Sterling Glaciation. However, the remains of Uktarra are still seen today. The Najer peoples still hail Kasaĵa Andamʊk as the true landmass they live in and the successor to a great supercontinent that collapsed long ago. The Syltoren & Nieden plates have not shifted in 36 million years due to them being remains of the Uktarran Plate, fitting them together like puzzle pieces unable to shift apart from each other. This makes Helmia, which sits at the plate boundary, one of the safest plate boundaries to live on in the world.
