Midgard is the world of the humans and giants, riddled with conflicts and opportunities. As one of the nine realms of the Circle, Midgard has been a battleground between the different creatures and entities of the Circle.

The Circle is the name used for the nine worlds that form the world tree Yggdrasil. Yggdrasil keeps the Circle intact, and if it falls, so does the Circle.

The Kingdom of Borrland is one of the major countries in Midgard, named after its first High King, Borri the Giant. He bent the tribes of modern day Borrland under one banner to fight the threatening "nightmen". The nightmen were men-like monsters from the darkness between the realms of the Circle, seeking death and destruction of the realms. They are described in ancient tales as shadowy figures, as dark as starless sky and cold as a deep winter night. Currently, Borrland's High King is Jorvi the Elder, a man of considerable age.

Valkyries are famed female warriors from Asgard, who hare known to choose those who die in battle. They are sometimes sent by Odin to aid humans to battle otherworldly threats, Odin is one of the gods of the human pantheon. He is revered as the god of wisdom, mysteries and warfare, among other things. He is the king of Asgard, and the father to many other gods and heroes of the past.

Skara the Raven was a renowned valkyrie during the days of Borri the Giant. She was sent by Odin, and is said to have been Odin's daughter by a human mother. She was trained in Asgard and cast down to Midgard without her memory. She fought agaisnt the nightmen and married Borri the Giant after he became the first High King. The nightmen were defeated and driven into near extinction by the humans. She gained the nickname "the Raven" for her coal-black hair and a raven wing tattoo on her back.

It is said that the spirits of the dead wander to the lands beyond the northern sea. They then meet the ferryman Gwynewhyr, who takes them to the underworld for a certain prize. The spirits have to tell the ferryman a secret. The ravens of Gwynewhyr then take the secret to Leofri, the keeper of secrets and the scribe of the gods.

Important feasts of Midgard's calendar are the midsummer and midwinter's Yule. There are twelve months in a year, and around 364 days in a year.
