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 an inhospitable 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.
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.
