Twilight of the Gods
Jotunheim, the realm of the giants, is thought to be the eastern edge of the world. The Jotun, or giants, who live there are known for their tremendous size and power, as well as the ability to change size and shape. Some are wise and others cruel; some beautiful and others hideous. The most powerful Jotun are a match for some of the Aesir and Vanir.
Jotunheim is a realm of vast scale, everything two or three times larger than in Midgard. The mountains of the stone giants literally pierce the sky, changing weather patterns and reaching far above the clouds. Animals are a mix of giant-scale, dire, and the familiar Midgard scale, as a few have slipped back and forth over the years.
Utgard, on the border between Midgard and Jotunheim, is a great walled fortress where contests and duels were held between the gods and the giants. Before war broke out, provoked by Sigyn.
Mimir’s Well is nestled amidst one of the vast roots of the World Tree where Odin went to learn wisdom – and take Mimir’s severed head back with him.
Thrymheim was the home to Thrym, the previous king of the frost giants. He was killed after being convinced by Loki to kidnap Idhunn from Asgard. Now his son Hrym lives there, and it is the functional capital of the frost giants.
At the edge of Jotunheim is an echo of Ginnungagap, the Yawning Void from which the world was created long ago.
Jotunheim is a Demi Plane connected to the Prime Material Plane by the Ethereal. It is mildly evil aligned and also has lower gravity than the Material.
