Serinor is a small world with a diameter of approximately 900 miles (roughly 1/10 the size of Earth, or 1/3 the size of Earth’s moon.) Its equatorial circumference is 2800 miles; at normal sailing speeds and assuming a ship could sail directly along the equator, a trip by boat around Serinor would take less than a month. Even with its small size, gravity remains Earth-normal. This is due to elemental and magical forces understood only by the fairies. Indeed, no other race would think to even ask questions about gravity, since they have nothing to which to compare it.

The most significant geological features of Serinor are the void mountains. Due to Serinor’s small size, even modest mountains can quickly rise above the troposphere and into the airless expanse known as The Void. The effects of high altitude begin to set in around 1000 feet above sea level. Journeys at eleveations above 2000 feet require some sort of magical protection against the environment; not even the most powerful magic can long save an explorer beyond 3000 feet, and many mountain ranges easily exceed this height. The continents of Serinor are criscrossed by these mountain ranges, creating individual weather cells and compartmentalizing much of the land in the world.

Sea levels on Serinor are relatively low, as most water is locked within the planet’s massive ice caps. Global sea cover accounts for approximately 50-60% of the surface area (as opposed to Earth’s 80%.)


Serinor is a cold planet. Summers are mild and short, and winters correspondingly long and fierce. The polar ice caps extend hundreds of miles outside the Arctic and Antarctic Circles. Populations tend to gather at sea level around the equator or in the tropics, which can still see noticeable cold seasons.
