The Hero witnessed Emperor Uriel Septim's assassination. Before he died, the emperor gave them the Amulet of Kings. He told them to take it to someone named Jauffre, and that Jauffre would know how to find his last surviving son. He warned that the assassins were in the service of the Lord of Destruction.
Savlian Matius told the Hero that he believes Martin is with a group that barricaded themselves within the Chapel of Akatosh inside the city. They need to follow his instructions in order to break the siege of Kvatch and rescue the survivors.
Weynon Priory is under attack. The Hero must find and protect Jauffre, but make sure that Martin remains safe from the enemy as well.
