This page of the guide contains information about the Historian - Everlasting side quest in Outriders. Here you will find a detailed walkthrough of the mission. Historian - Everlasting is the fourth side mission in Outriders. You will have to find items of interest to Madame Beauvoir.
This is a very short mission with several small areas. Iron ore deposits can be found in several places, so look around the location. Fight your way through the enemies until you reach the spot from the picture below. This is the last location and you will also find crafting resources there.
Eliminate all enemies on your way - you'll find the items Madame Beauvoir wants upstairs on the destroyed bridge.
