A "Noble" Event

If you are doing this as part of Legion Remix, you will have a crate item in your inventory once you accept the quest that has all the items needed for it.

Started from a quest item Torn Invitation which dropped for me in a Nightfallen cache. Each of the missions take 12 hours to complete without champion buffs and I only ever had one to complete at a time. Took me 3 days total to finish them all.

A note for priests struggling to find the turn in for this quest: If you have Alonsus Faol as your bodyguard follower, you cannot turn in this quest in Netherlight Temple because he will not be physically present in the temple to turn the quest into. You will need to remove him as your bodyguard at the mission table, and then you can turn in this quest as he appears next to the table.

Kind of annoying that this wasn't caught as a potential problem, and a GM couldn't tell me why I couldn't finish this quest because I didn't have any followers on missions.
