The Divide

"Nothing there? Like the Big Empty? The Sierra Madre? No, the Old World sleeps there, sure as the flag I carry. The Courier knows the way. And at the Divide, they and I - there, we'll have an ending to things."

- Ulysses

The Divide is a storm-wracked location in the vicinity of Hopeville in 2281.

Background
The Divide is a land torn apart by earthquakes and violent storms, where a major meteorological research project was undertaken by Big MT, in the vicinity of Hopeville. The event was said to have split the earth, destroying entire companies of NCR soldiers and cutting off supply lines along Death Valley Road and the Carson Pass Highway, granting Caesar's Legion time to recover after their loss in the First Battle of Hoover Dam. The road to the Divide is a long and treacherous one, and of the few to ever walk the road, none have ever returned.

There are rumors of survivors from the Divide, but these are viewed as legends, like the Sierra Madre, the Big Empty, and the Burned Man. In the future, the Divide is known to be the site of a battle between the Courier and Ulysses. The battle is described as taking place beneath the "Old World flag", with each participant carrying a "message" for the other. The battle seems to become legendary, and word of it spreads far and wide.

Appearances
The Divide is mentioned in Fallout: New Vegas, and all its add-ons Dead Money, Honest Hearts, and Old World Blues, and is set to appear in the upcoming add-on Lonesome Road.

Behind the Scenes

 * The Divide is likely the location (just named a "great divide" in Fallout Tactics) crossed by the airship expedition of the Brotherhood of Steel that damaged the airships and causing them to crash near Chicago, the event leading to the creation of the Midwestern Brotherhood of Steel.
