As the title suggests, I cannot leave the starting area for the Panda's because of a bugged quest - https://www.warmane.com/bugtracker/report/7720 ( Battle for the Skies - which has been confirmed).
I have made a ticket, but I also heard it's a very long time for it to be answered. And even if a GM will see that ticket and I might not be online. Then he/she probably won't be able to help me. Then again, waiting for a GM that might take hours, days and/or weeks. Sounds like a perfect recipe to waste time.
Al though I hope that's not the case. Not sure what else I can do.
I am currently next to Zhao-Ren in the quest area. He is on the ground, he doesn't move and he evades all attacks. All of the fireworks display the same message "Wait until the Onyx Serpent is directly overhead" even if I spam click them. Already remade the character and abandoned/accepted the quest multiple times.
Also cleared cache twice already. https://imgur.com/EwewPYo
So I've logged in this morning and it was automatically in the air just as I logged in. So I were able to use the fireworks. So from that moment I was able to complete it.
