On this page of our Assassin's Creed Valhalla River Raids guide, you will find the walkthrough for The Legend of Saint George quest. This mission involves finding two river map clues, which will unlock another map - River Dee.
Starting the mission
Mission beginning: Complete The Legend of Saint George quest.
1st St. George's clue
Map: River Severn.
Camp: Northern Monastery.
This clue lies on the table, among a stack of scrolls. You have to enter the building located in the western part of the monastery to get to it. Don't worry - if your companions set the building on fire, it will be safe until you leave the location.
2nd St. George's clue
Map: River Exe.
Camp: Escanceaster Monastery.
This clue lies on the table, among a stack of scrolls. To get to it you must enter the monastery. The door will be locked - you have to smash the stained glass window with your weapon and go inside. There are a lot of enemies inside. You can open the door and let your companions help you in a fight.
Unlocking River Dee
After getting both of Saint George's clues, return to Vagn. He will give you the River Dee map.
