You can find the Ardent Actor in front of the Provisioner, who will begin this Side Story. The actor’s next role is that of Sokrath, a legendary knight, but they are having trouble getting into character. There are two different solutions for this quest, with the first one requiring you to visit Grandport. Head to the Markets area and look for the Creepy Antiquarian in the northwest corner of the main bazaar section. Steal/Purchase the Sword of Sokrath, then bring it back to the actor to finish.

For the other solution, fast travel to Atlasdam and go to the Palace Gate area. Outside of the Royal Academy, there is a NPC on the left side, kind of overlooking the main section. This is the Handsome Minstrel and you will need to Inquire/Scrutinize The Song of Sokrath information from him. Once you have this info, bring it back to the actor in Everhold to finish.
