Jallenheim is a village in the province of Skyrim. In 2E 358, a note pertaining to the Dark Brotherhood was discovered in an abandoned house, once owned by a cobbler, who was believed to be a member of the Morag Tong. By then, the assassins' guild had been outlawed thirty-four years before then. The settlement is mentioned several times in the fictional book series The Adventures of Eslaf Erol. There is apparently a large palace in a park near the town center, owned by a nobleman.
Japhet's Folly is a fort on the inhospitable Rockjoint Island found northeast of Winterhold, off the coast of Skyrim in the Sea of Ghosts. It is known for its rough climate, lack of habitability, and tales of ghosts by the people of nearby Dawnstar. A sailor by the name of Japhet decided to build a large citadel here, only to pass away from the sheer cold and the isolation, hence the name.
Jehanna (also called Jehenna or Jelhana) is one of the eight major kingdoms in the province of High Rock, situated on the northernmost icy shores of Wrothgar. Nestled in the snow-covered forests of the Western Reach, it is described as being as beautiful as its name.
The Jerall Mountains are a mountain range on the border between Cyrodiil and Skyrim. They meet the Velothi and Valus Mountains at the Morrowind border, and the Dragontail Mountains at the Hammerfell border. The Jeralls are rugged, steep, and inhospitable, with only a few traversable passes. Of particular note is the Pale Pass, which was the site of the abrupt end to the First Akaviri Invasion in 1E 2703, after which its location was lost, only being rediscovered in 3E 433.
Jode's Light (alternatively known as "Ja'zennji Siir" in Ta'agra) is a ruined temple located on the borderlands of Reaper's March, in the province of Elsweyr. Named after the larger moon, Jode, the temple was founded as a sanctum and safe haven for every monk and acolyte, no matter the furstock or background they come from.
Jodewood is the southernmost subregion of the greater Reaper's March region. Jodewood is a border region between the provinces of Valenwood and Elsweyr, mainly lying within the borders of the former. The Crescent River ends here, flowing from the northern reaches of the March. The capital of the area is the city of Rawl'kha, a trading post in between the two provinces. The town of Willowgrove is a minor settlement known for its apiary and its brewery, which is used to make honeymead. The Do'Krin Monastery is an ancient Khajiiti temple dating back to the time of Darloc Brae. The ruins of Thormar are a known gathering place for worshippers of Baan Dar, who have been known to enter the Five Finger Dance from here.
The Jonelight Path is a realm used by Khajiit heroes as a shortcut to travel between the areas of Nirn. It is a place between all places and is named for Jone, the Khajiiti name for the smaller of Nirn's two moons. The realm appears to be a collection of floating islands connected by the paths of stars. The realm was described as full of moonlight.
It can be accessed in order to cross vast distances in a short amount of time. It is dangerous without an experienced guide. Prolonged stay in the realm may cause hearts of mortals to burst apart and their souls to be torn apart. Falling through gaps between the stars that act as parts of the bridges between floating isles in the realm is fatal. It is believed that only the swiftest champions of Azurah can survive in the realm for long.
One of the means of accessing the realm is utilizing the power stored in the body of Khunzar-ri. Ribs, femurs and claws are known to hold the power that can open the gateway to the Jonelight Path.
Passage through the Jonelight Path was likened to climbing the 'liminal forces that bind each here to every there'. How far and where one can reach through the Jonelight Path depends on the traveler. The Vestige was incapable of traveling far, but Khunzar-ri could utilize the Jonelight Path to reach any place and only he has heard Azurah's whispers and climbed the forbidden tree. Places where the Jonelight Path connects with the Nirn were described as 'liminal of here touches the liminal of there'.
Jorrvaskr is an ancient mead hall in the Skyrim city of Whiterun. The building was originally constructed from the hull of the Jorrvaskr, one of the longships used by the Five Hundred Companions to cross the Sea of Ghosts from Atmora. The ship's band decided to settle at the site of the ancient Skyforge, and the city of Whiterun subsequently grew around the mead hall.
Following the events of the Night of Tears and Ysgramor's return to Atmora and before the return of Five Hundred Companions Ysgramor expressed a desire to immediately return to Jylkurfyk to take a ship back to Tamriel to avenge his kin. However, before he returned to Skyrim he codified the written language in Atmora to preserve human history.
Due to an inexplicable shift in the climate of Atmora territories once known as a green, albeit cold land were gradually overcome by "the frost fall" and rendered largely barren and uninhabitable, becoming a "frozen continent".
Although there is some suggestion that, as of the early Third Era, Atmora was still inhabited, the fate of Jylkurfyk is unknown. It is believed that Atmora no longer supports any civilized life, and those people who did not leave it for Tamriel ultimately succumbed to the ever-worsening climate.
