There’s a rough map up on the Maps tab.
Midgard is a small world with only one continent (also called Midgard). The continent is circular, roughly 300 miles in diameter, and covers nearly half of the planet’s surface area. The world tree Yggdrasil grows from the center of the continent, so massive it can be seen from anywhere in the northern hemisphere, so tall its boughs are lost among the clouds. Yggdrasil is surrounded by the Great Forest, home to the elves. The forest is ringed by a circular mountain range, home to the dwarves and gnomes. From the mountains to the sea are vast fertile plains, home to men. The seas are dotted with many small islands, home to the halflings.
Several geographical features stand out on the continent. While the coast is mostly a mix of cliffs, fjords, and rocky beaches, there is one sizable harbor, known as the Scar. Long ago, some forgotten cataclysm blasted the shore here, creating a small inlet and driving up a protective range of rugged hills around it. Due to the conducive geography, the Scar has long housed the largest human settlement on Midgard, and is also the site of an annual market, the one time of year all the races come together. Historically, this large village has just been referred to as The Scar, but lately its inhabitants have adopted the name Miklagard. The river Brutt flows from the mountains toward the Scar, splitting at the hills into an eastern and a western fork.
The mountain Dvergfjell is the highest peak on Midgard and stands several miles apart from the rest of the mountain range. Given its prominent position, it’s long served as a primary point of contact between the subterranean races and those on the surface. The dwarves and gnomes have built it up as both a strong fortress and impressive example of their craft. The richest of men, elves, and halflings come to Dvergfjell to hire craftsmen. The river Gull flows from the base of the mountain. Wizards and prospectors live along the river, hoping to siphon off some of the valuable effluvia produced by the people under the mountain.
Numerous small glades and copses dot the plains of Midgard, but the only true forest outside of the inner ring is the Small Forest, which is thick with hunters, beasts, outlaws, and the occasional elf. Mani lake lies at the center of the forest and is a holy site to the druids of Midgard. The continent’s third major river, the Stjerner, flows from Mani to the sea.
With a good ship and the right magic, one can sail to either Jotunheim or Vanaheim. Both of these realms mirror the geography of Midgard, but with significant differences. Jotunheim is a land of rough seas, violent storms, and feeble soil. The orcs, goblins, giants, and so on, supplement the meager resources of their realm by raiding Midgard. Vanaheim, on the other hand, is more idealic and fertile than Midgard. The Vanir look upon the people of Midgard kindly but are proud and aloof and don’t always welcome visitors.
If one could climb the world tree, one would enter Alfheim, the land of the Light Elves. Travel to Alfheim is rare, but those who have been describe it as lush, beautiful, and dangerous, full of magic beyond the comprehension of man. Scholars suggest that one might travel between Alfheim, Asgard, and Muspelheim, but this has not been confirmed. No living soul has entered Asgard or Muspelheim and lived to return.
Legends say that Svartalfheim might be reached by tunneling among the roots of Yggdrasil. An inverse of the celestial realms, Svartalfheim may provide access to Hel and Nifilheim.
