It’d be interesting to see a third shift in Forsaken core values. They started out hungry for revenge, then moved on from that to surviving in a world that despises them, earned or not. The third core shift for the race could be in the wake of the Shadowlands. We’ve seen it now. We also know that becoming Forsaken is not necessarily instant damnation, unlike how it’s been hinted in the past.
Religious values regarding death, for better or for worse, are inevitably going to change now that we’ve seen that: Souls are judged by an Arbiter. Souls are then sent to the best* afterlife deemed by said Arbiter and the main function afterlives are themed around redemption, reincarnation (only for gods though), transportation, and defense. No longer is it as simple as what you believed prior.
*Best for the soul, best for the Shadowlands, or best for maximizing anima potential?
Either way, everyone’s thinking about death and likely restructuring their values around it. Some people might not approve of this. Traditions are difficult to shift in a single generation. So perhaps Azerothian would like something a bit more familiar that places choice into their hands. Thomas Zelling stands as an example here.
Maybe under a less aggressive mindset the Forsaken could present themselves as an “alternative afterlife”. Prior to Shadowlands, undeath and the Scourge were seen as manifestations of death itself, after all. Why not present it as exactly that, a new death?
If you know you’re dying and you don’t like your fate being decided by another, go to Lordaeron and become raised as a Forsaken. Or set that in your will. Or your family can decide if you never indicated either way. Worst comes to worst they put you back down if you rise up and don’t like it.
It also stands as a logical evolution to the newer mindset by Forsaken that they would like to remain in the world and need to reproduce in order to do so. This time without forcing it on others.
I could see this becoming more spiritual too. As was mentioned earlier in the thread, imagine a sort of Cult of Forgotten Shadow/Dark Catholic style faith where you undergo very symbolic and grandiose rituals regarding the rebirth of another into a new Forsaken, or the returning of Forsaken to the veil.
Add to it some complex theology regarding other facets of their stewardships over death, like visitation rights for living, and you have a very fascinating and deep system with lots to explore. Imagine as well what relationship you might have between the state and the faith. Who’s calling the shots? Is it shared? Or is it entirely a theology?
Lordaeron could become this strange, death haven that treats itself as “above mortals” and truly like a whacky successor to an afterlife system they do not seek to participate in. Maybe even the prevalence of necrotic magic would truly begin to transform the land. Borders become static and eventually both undead and living settle into a mindset of leaving both worlds alone.
Of course not everyone believes in a world of sunshine and happiness though and both living and dead might not be content with this setup, leading to some good ol stories from that.
