Received from: automatically after finding all five pages [The Circle Tower]
Description: This quest will appear on your list once you've collected all five pages and in order to do that you must start clicking on certain objects found inside the tower. Make sure to go to [The Circle Tower - The great hall] before you start looking (M34, 11).
Once you've successfully collected all five notes leave the tower and head to a different location. You'll soon take part in a random encounter during which you'll have a chance to meet Beyha Joam. Have a little chat with him and then attack him. Don't forget to eliminate a mage seen on a nearby field before dealing with the main boss.
