Jötunheimr

Jötunheimr (ヨツンヘイム) is the most difficult field of «ALfheim Online». It is described to have a frigid and dark environment and infested with evil god class monsters and an inverted pyramid containing the «Holy Sword Excaliber». It is said that there are various entrances to this dungeon, one such entrance would be to encounter a large worm mimicing a village around the Aarun Plateau. The other entrances would be at the end of the dungeons located North, South, East and West of Aarun City. There is also a secret doorway located at Aarun City that leads directly to Jotunheim but one would require a key to open the doorway and a Flying «Beast Type» evil god class monster to approach the surface of Jotunheim.

There are two types of evil god class monsters, one is «Humanoid Type» the other is «Beast Type». The humanoid types are controlled by King Priam, the beast class is under the protection of the three fates of norse mythology, Verdande, Urd, and Skuld. According to Urd, Jotunheim was once like «Alfheim», with the blessings from the world tree Yggdrasil, covered in the beautiful water and greenery. Urd and her tribe, the Rock Giant Tribe, lived in harmony with the «Beast Type» monsters currently in this dungeon. After stealing Excaliber, King Priam threw the sword to Urd's Spring which is the center of Jotunheim. The sword severed the thick roots of the world tree, and in that instant, Jotunheim no longer received the blessings from Yggdrasil. Where there was once a great lake now is know as the «Great Void», and directly above the void is the inverted pyramid made of ice which was once part of the lake that is now frozen, and inside the pyramid lies the «Holy Sword Excaliber».

During the events of Caliber, players were given a quest to retrieve Excaliber by defeating the «Beast Type» evil god class monsters. This quest was soon revealed to be a fake and if it were completed would lead to the invasion of the upper world of «Alfheim» by the «Frost Giant Tribe» or also known as the «Humanoid Type» evil god class monsters. The real quest to obtain Excaliber required players to talk to the NPC Urd and accept her quest to venture into the inverted pyramid housing the sword and remove it. Before removing the sword, players need to battle King Priam as a boss. After completing the quest, the party receives Excaliber and restore Jotunheim to its former glory.
