I just noticed this official announced in the launcher:
Summer Festival Extended!
We have extended the Summer Festival! You may now enjoy the festival through Monday August 12. We are also increasing the drop rate of loot boxes throughout the world this weekend from Friday August 9 – Sunday August 11. Enjoy!
Yay! That’s good news 🙂 I’m guessing Sheherezi will do some quests for the Inn League and the Ale Association after all!
