- Travel to the specified city.
- Go into the weapon smith and kill the warrior.
- Return to the questgiver to complete the quest.
To start the quest, the Hero must have a reputation of at least sixty within the Dark Brotherhood. Speak to any questgiver within the guild and they will inform the Hero they have to kill an old warrior that fought in the War of Betony.
Upon traveling to the radiant city, you must go to the weapon smith that the warrior is located at and kill him. There is an equal chance that the warrior will either be a barbarian, a monk, a ranger, or a ancient vampire.
If the Hero doesn't complete the quest within specified time limit, they will lose reputation with the guild.
