This is what I think would fit for the forsaken undead as a heritage armor questline/scenario. Based upon the plot developments in Before the Storm, BFA, Shadows rising, Shadowlands, and Exploring Azeroth: Eastern Kingdoms.
It will mainly take place in Tirisfal and the above ruins of Undercity. As the blight there have started to dissipate and with some more time and some cleanup work we would probably have it be visitable soon.
We learned in EA:EK and BTS that the people of Lordaeron never wanted the Menethil crown (a metaphor for royal line) forgotten, the very real Menethil crownās location is also now known.
Lilian Voss is currently acting as the voice of the Forsaken but itās a position she has no interest in and she does not want to lead. On the other hand, we have another person very interested in the Forsaken and their place in the world, that also attend meetings between world leaders learning from Lilian. It just so happens that this person is also from the old Menethil royal line and the person next in line for the crown.
I hope you can see where Iām going with this.
The Heritage quest will be the coronation of Calia Menethil, of the Lordaeron kingdom, Queen of the Forsaken. She will serve as a bridge between the undead of Lordaeron and the living, between the Horde and the Alliance, as she is on good terms with both.
Now for more of the details of the quests themselves.
We start up by talking to Lilian, Calia, and Alonsus Faol.
Then there will be several quests where we get things in order for the Coronation, some decoration, etc, but also quests where we talk to Lilian, Calia, and Faol on what it means to be forsaken, and more importantly a Lordaeronian. (I decided on this from the Worgen heritage armor, where they discuss how itās not the curse that makes you a Gilnean. As I think it fits.)
Then weāre also sent to go retrieve the crown of Menethil, hidden in the shallow grave at the Stormwind lighthouse.
When weāve done that, itās time to witness the Coronation.
It takes place in the throne room of Lordaeron, the crowd reaches all the way outside though. In the crowd is forsaken but also living Lordaeronians that returned to witness the coronation and meet their long lost forsaken friends and family without the fear of death.
More notable characters will be the Horde leaders, but also Anduin, Turalyon (this paladin is originally from Lordaeron), and her friend Taelia Fordragon.
Voss will give a speech, signifying her stepping down and leaving them in good hands, Faol will place the Crown of Menethil upon Caliaās head and she will sit upon the throne. The same throne her father and forefathers sat on.
And the bells of Lordaeron will chime in celebration with the cheers of her people (a callback to wc3 with the bells and cheers when Arthas returns home), from both the living and the dead on this day.
Thoughts on this?
