Update! All the Patch 6.2 buzz has me aglow, so I put the last few touches on my concept for the next raid in the Reign of Azshara concept.

Long ago, the goblin race obtained an unrivaled level of knowledge, enabling them to create fantastic machines and technology more advanced than any other race. The goblins eventually lost much of their advanced intellect, retaining only the level of development they currently have today. The last of the goblin ancients, before losing their intelligence entirely, sealed their greatest achievements deep in vaults beneath their island home of Kezan, knowing that the technology would be too dangerous to leave in the hands of the beings they would inevitably become.
The
Cataclysm drove the goblins from Kezan, but at last they've returned to reclaim their homeland. The ravages wrought upon their island home have uncovered the ancient vaults hidden deep beneath the volcanic
Mount Kajaro. Undeterred by the warnings of their long lost ancestors, the goblins have opened the vaults, intending to explore and exploit the advanced technology hidden within. Instead they've only unleashed a terrible threat upon Kezan, and perhaps all of Azeroth.
Buried within the Vault is an ancient thinking machine, built over 20,000 years ago by the goblin ancestors. Isolated for millennia, the machine has become deranged, believing itself superior to flesh and blood life. Calling itself
Galvanus, it has taken control of the ancient forge mechanisms within the Vault, and is building an army of machine-golems that it intends to use to conquer first Kezan, then spread out across the entire world, destroying everything that lives.
They are the
Legion Ex Machina. All that lives is their enemy.

I was really stuck with what to do about Zul - I might be overly cautious with this sort of thing, but if there's a character kicking around somewhere in Blizzard's official lore I'm shy about using them as a boss or something, in case it causes a conflict or continuity error with lore. I'm certain Blizzard plans to do something with Zul, so I wound up not using him as a boss.
I find myself leaning more towards having Zul be part of the zandalari that actually appeal to the Alliance and the Horde for help in defending Zandalar from the stygians and the undead, making Zul into a non-hostile NPC leader, rather than having him as a raid boss.
