Ashlan can be found right next to the equipment shop in S’warkii, and he wants to know more about the monster tamers, although he doesn’t know who to ask. In order to complete this Side Story, you will need either Alfyn or Cyrus in your active party. Head into the tavern to your southeast and Inquire/Scrutinize the Old Storyteller inside to obtain the Tale of the Beast Tamers information. Bring this back to Ashlan to complete the quest.
