The Vernim Woods is a large forest that makes up a large portion of the Autumnal forests in the Riften Hold. A settlement known as Vernim Wood was established in the general area in the third era.
The Vernim Woods are located along the northern roads of the Rift and mark the border between the Stony Basin and the Ragged Hills regions of the Rift. The Vernim clearing in the middle has a large Nordic tomb known as the Vaults of Vernim that gave the forest its namesake.
During the Interregnum in 2E 582, the Boneshaper Clan of Reachmen made an alliance with the Order of the Black Worm to destroy the Ebonheart Pact in the Rift. The Boneshapers attacked the town of Shor's Stone and Fallowstone Hall to garner the necessities to resurrect Sinmur, the Giant of Legend. The Boneshapers had advanced to the Vernim Woods and had kept the Pact at bay for a while. The Worm Cult was performing a ritual on the Reachmen and the Pact needed to stop the rituals before it gets out of hand.
A mysterious traveler that was known as the Vestige traveled to Vernim and uncovered the plot between the Reachmen and the Worm Cult. The warrior took the heart of Calix Thorntongue and several other cultists and used it to create a potion to enter the Vaults of Vernim. Inside the vaults is Stral Blackthroat, the leader of the Reachmen, and defeating him would drive the Reachmen out of Eastern Skyrim. The Vestige defeated Blackthroat, and the Worm Cult vanished into the Ragged Hills. Reports say they arrived into Nimalten.
During the Imperial Simulacrum in 3E 399, the Vernim Wood township existed in Skyrim in between the towns of Reich Corigate, Pargran Village, and Dragon Wood. At one point, the Eternal Champion had visited the city in their quest for a piece of the Staff of Chaos to defeat Jagar Tharn at the Imperial Palace.
