The similarities are obvious but curious what people currently think about these two races atm. What's the connection?
To me it seems like the same 'race' but slightly different, sort of like Void Elves and Blood Elves. If you look at all of the Ethereal technology and architecture shape design in Outland and Argus then go look at Brokers in Shadowlands seems like cultural links are present.
Both Ethereals and Brokers seem timeless and not necessarily tied to life or death.
One thing I considered is maybe the body vessels are powered remotely like a drone from a distant planet.
I want to hear what everyone else thinks.
