I have not seen a thread on this yet so I decided that I will make it.
It seems like Vol'jin will become the new Loa of Kings from datamined text on wowhead.
"I thought I sensed something special about your spirit. You have a loa within you... waiting to be reborn.
I cannot promise that you will survive... or what form of loa you will become. But I shall allow you a pod to be reborn.
Life be full o' mysteries. I be learnin' ta embrace dem and see what happens next.
<Scene swaps to Vol'jin being put into a pod, then slowly fades to black... before snapping back to Bwonsamdi standing in front of Vol'jin's pod.>
Rezan be smarter dan I thought... but now dere be a new loa who be havin' a deal wit ol' Bwonsamdi. Heh heh heh..."
From what I gather is that Rezan imbued part of his spirit into Vol'jin, and now at the end of his storyline Vol'jin will become a new loa with the Winter Queens help. It has been strongly hinted that Vol'jin would become a loa during his questline with Zalazane in BFA.
What are your thoughts on this? Do note this is still Alpha text and could be subject to change.
