Lyzoy

The lyzoy on Eufez are its most striking feature and are believed to initially be the remnants of an ancient flood which impacted the planet's former supercontinent sometime during the late Crejassic period. The impacts and collisions of later asteroids are then believed to have exaggerated the already existing geological formation of these continental strips. Geological limestone molding seen on certain coastal mountain ranges display an origin with these impacts, which are believed to have pushed sedentary rock surrounding the lyzoy to above sea level.

Lyzoy are separated by wide straits called rims, and are usually composed of sedimentary rocks. The composition of each rim varies depending on its location. The eastern rims consists primarily of sandstone and mudstone, whereas western rims contain mainly clay, silt, and gravel. The crust beneath the lyzos is believed to be made up of metamorphic basalt, which makes up the majority of the northern continent. This crust is subject to the movement of tectonic plates and is slowly breaking apart from the mainlands. It is estimated that they may be entirely separated within 511 million years. Despite the soft crust of lyzoy, underground dwarven settlements are not as common as one would believe.

The length of each lyzoy varies greatly with the average length totaling at 506 km. Some strips are bordered by several dotted islands each separated by narrow straits, and then in groups by stretches of open water. These long and relatively thin stretched arms of land make up roughly half of the continental surface area of Eufez. The majority of the planet's population lives within these areas, although smaller communities outside of the lyzoi. Many lyzoi regions are dominated by large lakes which mark the divisions of their winding arms.

Large bodies of freshwater include Lake Sibir, Lake Bakhchisarai, and the Aldi Sea.

It is not known why lyzoy are less prevalent in the northern continent, but theories have been presented about the possible causes of this phenomenon. One theory proposes that the north had a higher concentration of volcanic activity throughout the early part of the planet's history, leading to the formation of numerous lava flows which covered much of the northern hemisphere's lyzoy. Evidence of basaltic bedrock has been found along the edges of certain northern lochs. A second explanation posits that the north's geographical nature has been influenced by its dragon inhabitants, or that the elemental crystals have an influence on lyzoy (this has been disproven). More recent ideas have suggested the mixing of cold and hot waters, drift ice, and the solitary movement of the arctic plates.
