A Bard’s Calling Quest
The sixth chapter starts with Linzi asking you to take her to the Rushlight Tournament. Let her go there by bringing her into your squad. You’ll find the girl in the lower part of the location. Talk to her and another girl standing next. Then you just have to return to the capital and talk with Eobald in the throne room. After that, you’ll have to wait for work on the book to finish.
When it’s finished, you’ll receive an invitation to Pitax. Head for the town and come to the academy where you need to talk to the girl standing on the top of the ladder. Now all that’s left is to bring down Irovetti.
